How to File a Fatburger Complaint
Because many Fatburger restaurants are operated by franchisees, the exact restaurant location is important when requesting assistance. Follow these steps:
- Contact the restaurant manager: For a recent order, missing item, cold food, incorrect preparation, cleanliness issue, wait-time complaint, or employee interaction, begin with the location that handled the order.
- Keep supporting information: Save the receipt, order number, restaurant address, visit date, approximate time, items ordered, photographs, and delivery confirmation.
- Submit written feedback: Use the official Fatburger Feedback form. Explain what occurred, the location involved, whether you contacted a manager, and the resolution you are requesting.
- Follow up: Keep any confirmation or case number. If the complaint remains unresolved, follow up through the same channel so the company can connect the messages.
- Use the corporate office when appropriate: The Beverly Hills address and corporate number are better suited to corporate or formal business matters than routine restaurant support.
Order, Refund, Delivery, and Food-Safety Issues
- Incorrect or missing restaurant order: Contact the restaurant that prepared the food and then submit the official feedback form if necessary.
- Third-party delivery order: Contact the delivery service for driver problems, delivery delays, cancellations, missing-order credits, and refunds controlled by that provider. Contact Fatburger when the restaurant prepared the food incorrectly.
- Duplicate charge or refund: Provide the restaurant, order date, amount, payment method, and confirmation number privately. If an unexplained charge remains, contact the card issuer.
- Food quality or safety concern: Contact the restaurant promptly and preserve the food, packaging, receipt, and photographs when practical. Serious sanitation concerns may also be reported to the appropriate local health department.
- Allergic reaction or medical emergency: Seek appropriate medical or emergency assistance immediately instead of waiting for a customer-service response.

Who Owns Fatburger?
Fatburger is owned by FAT Brands Inc., a restaurant franchising company whose portfolio includes Fatburger and numerous other restaurant concepts. Searches for the “Fatburger corporation” generally refer to the brand’s corporate operations under FAT Brands.
FAT Brands commenced voluntary Chapter 11 proceedings on January 26, 2026. The company stated that Fatburger and its other restaurant brands were expected to continue operating as usual during the restructuring. Chapter 11 concerns the parent company’s financial restructuring and should not be interpreted by itself as an announcement that every Fatburger restaurant is closing.
Fatburger Company History
Fatburger’s history began in Los Angeles in 1947, when founder Lovie Yancey and her husband opened a small hamburger stand called Mr. Fatburger. After the couple separated in 1952, Yancey removed “Mr.” from the name and continued the business as Fatburger.
The brand became known for customizable burgers, hand-scooped milkshakes, fries, onion rings, and its “Last Great Hamburger Stand” identity. Fatburger later expanded beyond California through franchised and co-branded restaurants in the United States and international markets.
Fatburger’s Competitive Landscape
Fatburger competes with national and regional fast-food and fast-casual burger restaurants. Major competitors include McDonald’s, Burger King, Wendy’s, Jack in the Box, In-N-Out Burger, Five Guys, and Shake Shack.
Fatburger differentiates itself through its Hollywood and Los Angeles heritage, customizable burger sizes and toppings, nostalgic branding, and a menu positioned between traditional fast food and fast-casual dining.
