How to Increase Restaurant Sales and Customer Retention - 15 Proven Ways

1. Play the Right Background Music

Music isn’t just background noise—79% of customers notice background music, especially in restaurants. But the wrong music can hurt sales.

A global restaurant chain found sales dropped 4.3% when playing random hits, compared to no music. However, sales jumped 9.1% with a mix of hits and lesser-known, brand-aligned tracks. Even a 3.6% boost came from balancing popular and niche music, while dessert sales soared 15.6%.

That variety is key—restaurants that played a mix of popular artists and less famous ones in a playlist that fit their brand saw sales increase 3.6% over restaurants that played only brand fit hits. 

Your ideal playlist depends on your brand. A college hotspot might go for upbeat indie, while a retro diner thrives on nostalgic tunes.

2. Leverage Menu Engineering to Maximize Sales

Did you know that menu design can increase restaurant sales by 15%? By analyzing sales data and customer feedback, you can identify your most popular and profitable items and use menu engineering techniques to highlight them.

Use strategic design elements such as bold fonts, enticing images, color boxes, arrows, and creative descriptions to guide customer choices. Feature high-margin dishes, add-ons, and signature cocktails prominently to encourage upselling.

3. Optimize Food and Drink Offerings

Once you’ve identified your best-selling and most popular menu items, focus on those. Cut menu items that don’t elicit positive customer feedback or don’t sell enough to be worth the costs of ingredients and preparation. This will give you a starting point to explore new and exciting offerings with a data-driven approach.

A well-curated menu improves profitability, boosts online reviews, and encourages word-of-mouth marketing, which is a powerful and inexpensive way to reach new customers. Highlight popular items, run limited-time specials, and promote standout dishes to attract and retain customers.

4. Ensure Restaurant Staff Are at the Top of Their Game

First impressions shape dining habits and purchasing behavior, making them crucial for any restaurant—especially high-end establishments. A positive, memorable first experience increases the chances of customer retention and word-of-mouth recommendations.

Service quality is just as important as food preparation. Orders should be accurate and delivered promptly. Approximately 39% of diners say they would not return if they saw staff handling food without gloves. Poor service deters 50% of customers (rising to 63% for baby boomers), while long wait times drive away 25%.

Happy, engaged employees create better customer experiences. According to the Harvard Business Review, employee recognition boosts morale and productivity. Simply acknowledging staff efforts, listening to concerns, and taking action to resolve issues fosters a positive work environment. Consider incentives like bonuses, gifts, or a customer-of-the-week program to further motivate employees and enhance service quality.

5. Prioritize Cleanliness 

Cleanliness is a deal-breaker—90% of American diners consider it crucial, and 25% leave negative reviews for hygiene issues. Cleanliness issues can not only ruin the customer experience but also damage a restaurant’s reputation.

Here’s a breakdown of the top reasons customers would refuse to return to a restaurant, with both overall percentages and segmented by generation.

Notice how many of these are related to cleanliness. Approximately 82% of customers would not return to a restaurant if they saw rodents or insects, 45% would be deterred by unpleasant odors, 44% would avoid coming back if plates or utensils were unclean, and 31% would skip a return trip if the bathrooms were dirty.

Contaminated food and unhygienic food handling practices are also high on the list.

Train staff to maintain a clean space both in the front of the house and the kitchen. Here’s a sample checklist:

• Remove clutter, stains, and visible dirt.

• Replace furniture if necessary.

• Sweep parking spaces in front of the building to remove leaves, nails, and debris.

• Regularly clean windows and food display cases. Ensure there are no flies on the food under the glass.

• Thoroughly clean glasses, plates, and cutlery. There should be no water streaks, lipstick stains, or leftover food on these items.

• Regularly clean the bathrooms, and ensure soap and paper towel dispensers are continually refilled (or that paperless hand dryers are in good working order) so customers can feel clean when they sit down to eat.

A clean environment helps ensure restaurant customers feel comfortable and want to return with their friends and family.

6. Run Ads with Special Offers or Coupons

A strong marketing strategy keeps your restaurant competitive. Target ads where your customers spend time—if they’re on social media platforms like TikTok or Instagram, focus your efforts there.

Build an email list to promote events and special menu deals. Time-sensitive discounts, like daily or seasonal specials, drive urgency and boost sales.

Whether you’re a new restaurant or a household name, partnering with local businesses for cross-promotions, or sponsoring local events by offering gift cards as prizes, can increase foot traffic and attract customers.

Offer first-time customer deals and a loyalty program with perks like free drinks or appetizers. Train staff in cross-selling and up-selling to highlight promotions and new menu items, maximizing each guest’s spending.

7. Offer Happy Hour and Brunch Specials

Time-specific menus drive sales. Restaurant revenue statistics reveal happy hour accounts for 60.5% of bar and restaurant alcohol revenue for restaurants that serve alcohol. Even with discounts, the average bill during happy hour is $68.99, which is approximately $8 higher than average.

Recent inflation had an unexpected effect on happy hour traffic. Casual dining saw weekday traffic rise 9% over the course of a year, and weekend traffic jump 13% during the 4 to 7 p.m. time slot. Brunch specials also attract steady crowds, boosting sales during slower hours.

Meanwhile, limited-service concepts saw a 20% increase on weekdays and a massive 25% increase on weekends.

8. Maintain a Strong Social Media Presence

Half of diners say social media influences restaurant choices, and 22% return due to a strong online presence. Used effectively, it boosts revenue, engagement, and brand recall.

Customers follow businesses that post useful or entertaining content. If they like your restaurant, they may search for it or follow after seeing a valuable ad. Regularly share specials, events like trivia night, bingo, or karaoke, and high-quality photos of food and drinks—think frosty cocktails on a sunny patio or steaming comfort food on a cold day.

Inconsistent posting or low-value content leads to lost followers and buried posts by algorithms. However, managing every platform is time-consuming, so focus on where your target audience spends time.

9. Host Live Performances and Events

Live music and special events create unique experiences that attract customers. Approximately 75% of diners will stay longer when they enjoy the music, leading to higher sales. Feature local musicians, themed nights, art showcases, or chef’s table dinners to attract new customers and encourage repeat visits.

In addition to staying in the restaurant, here are other things survey respondents were likely to do if they enjoy the music in a restaurant:

Consider featuring up-and-coming local musicians and artists that fit your brand to engage with your community on a deeper level.

10. Invite Customer Feedback

Customer satisfaction hinges on details like cleanliness, food quality, service, background music, and atmosphere. Understanding how diners perceive your restaurant helps improve their experience.

About 94% of diners check online reviews before visiting, and a one-star increase can boost revenue by 5-9%. To gather feedback, use surveys, feedback cards, and encourage satisfied guests to leave reviews. To increase engagement, encourage reviews through promotional campaigns such as discount offers and email marketing campaigns.

11. Optimize Your Google Business Profile

Your Google Business Profile (formerly Google My Business) acts as your online storefront—keep it updated with the correct address, hours, phone number, website, and reservation links. Double-check a.m./p.m. settings to avoid confusion.

Use this space to share specials, events, social media links, and high-quality photos. Maintain Google Reviews by responding to all feedback, especially negative reviews. Stay polite and professional, offering discounts or free items to dissatisfied customers. While this may not change their opinion, it reassures potential customers that you take complaints seriously.

For hostile or spam reviews, respond calmly to reduce their impact. Report suspicious reviews—such as those from new accounts, irrelevant comments, or exaggerated claims—to Google.

12. Update Your Website

Approximately 77% of diners check restaurant websites before visiting. An outdated, confusing, buggy, or unintuitive website can have a direct negative impact on restaurant sales.

Of survey respondents, 68% were discouraged from visiting a restaurant by a bad website, and 62% were discouraged from ordering delivery or takeout.

The quality of the food photos on the website, readability of the menus, mobile-friendliness, and the currentness of the web design all impact a potential customer’s decision to patronize a restaurant.

Further, a restaurant’s website can influence a customer’s decision to dine in or order delivery.

Search engine optimization (SEO) can help your website rank higher in Google, making it more likely that potential customers will find your restaurant. 

13. Create a Welcoming Atmosphere

Encouraging customers to stay at a restaurant longer is one of the most straightforward ways to improve sales. Customers who have a reason to stay will often order more drinks, desserts, and other menu items. This can not only improve your bottom line but also foster customer loyalty.

Cultivate a welcoming, engaging atmosphere with comfortable seating, soft lighting, intentional decor, and a playlist that fits your brand. Offer free Wi-Fi and ensure wait staff frequently refills water glasses and soft drinks. A welcoming ambiance and exceptional service can promote a sense of belonging, encouraging customers to stay longer. 

14. Embrace Technology

Modern technology streamlines restaurant operations, enhances guest experience, and boosts restaurant sales. Creating an online ordering system or leveraging food delivery services like DoorDash can help restaurant owners expand their customer base and reach new demographics.

Digital payment options and restaurant analytics improve efficiency while driving customer retention. Advanced point-of-sale (POS) systems simplify payments. Tap to Pay is replacing card swipes, and some restaurants use tableside tablets for ordering and checkout.

Customer relationship management (CRM) tools help track customer data, enabling targeted marketing, promotions for birthdays and special occasions, and rewards programs that increase lifetime value.

Technology can also optimize table turnover and staff performance while analyzing sales trends and inventory levels to refine menu planning and pricing.

15. Invest in a High-Quality Sound System

Poor sound quality—crackling, distortion, or rattling speakers—can ruin the dining experience. A high-quality business sound system enhances ambiance, ensuring restaurants fully benefit from the sales and retention boosts that well-curated music provides.

Even the best playlist or atmosphere falls flat with subpar audio equipment, making sound quality an essential investment.

How To Increase Restaurant Sales: Enhance the Customer Experience

Ultimately, increasing restaurant sales and customer retention comes down to one thing: creating an exceptional experience. Music plays a significant role in shaping customer perceptions and influencing spending behavior.

However, playing music legally requires proper licensing, such as public performance licenses. Soundtrack offers over 100 million fully licensed tracks and 1,300 customizable playlists. It’s the only service that truly allows you to play what you want, when you want, and its AI Playlist Creator allows you to generate brand-fit playlists from simple text prompts.

Most importantly, the service gives you peace of mind that all the music you play in your restaurant is properly licensed and that you’re protected from potential lawsuits.
