Big Boy Restaurants

Big Boy is an American casual dining restaurant chain headquartered in Southfield, Michigan; it is currently operated in most of the United States by Big Boy Restaurant Group, LLC. The Big Boy name, design aesthetic, and menu were previously licensed to a number of named regional franchisees. The parent franchisor company has changed over the system's lifetime: it was Bob's Big Boy from 1936 to 1967, then Marriott Corporation until 1987, then Elias Brothers' Big Boy until 2000. Since 2001, control of the trademark in the United States has been split into two territories, between Big Boy Restaurants in most of the country, and Frisch's Big Boy as an independent entity in a few states in the Midwest.

As of May 2025, Big Boy Restaurant Group operates 61 total locations in the United States: 51 "Big Boy" branded restaurants in Michigan, Nevada, North Dakota, and Ohio; 6 as “Dolly’s Burgers and Shakes” in Frisch’s territory; and four additional locations in California branded as "Bob's Big Boy". One Big Boy location also operates in Thailand. Frisch's operates 31 Big Boy restaurants in the United States, of which 13 are franchised. Big Boy Japan, also independent of Big Boy Restaurant Group, operates 274 restaurants in Japan.
