Founded in 2010 by Tom Armenti in Fort Collins, Colorado, Fat Shack has rapidly become a notable name in the fast-casual dining sector. The company is currently headquartered in Denver, Colorado. After opening its first location, Fat Shack began franchising in 2015, expanding its unique dining experience to various regions across the United States.
Fat Shack's menu is renowned for its "Fat Sandwiches," which are loaded with a variety of ingredients, offering a hearty meal option for customers. Beyond these signature sandwiches, the restaurant also serves burgers, wings, appetizers, desserts, and a selection of hot and cold beverages. This diverse menu caters to a wide range of tastes and preferences.
What sets Fat Shack apart from its competitors is its commitment to satisfying late-night cravings with an innovative and indulgent menu. The brand's focus on hearty, flavorful offerings has garnered a dedicated customer base, particularly among those seeking substantial meals during late hours. This distinct positioning in the market has contributed to Fat Shack's growing popularity and expansion.
Here's what you would need to invest if you were to start this franchise. These costs are provided by the franchisor in the Franchise Disclosure Document.
Fat Shack provides comprehensive training to its franchisees through multiple structured programs. Here are the main types of training offered:
Fat Shack grants its franchisees a defined geographic area known as a "Protected Territory," which generally extends in a three-mile radius from the front door of the restaurant.
Within this zone, the franchisor agrees not to open or allow another third party to open a Fat Shack restaurant, provided the franchisee remains in substantial compliance with the franchise agreement. This arrangement aims to provide some operational buffer and reduce direct competition from the brand within close proximity.
However, Fat Shack does not offer exclusive territorial rights. The franchisee may still face competition from other franchisees or company-owned outlets, as well as from alternative distribution channels controlled by the franchisor.
