About Bob Evans Restaurants (from Wikipedia)

The Bob Evans Restaurant chain started from a single truck stop diner near the Bob Evans Farm in Rio Grande, Ohio (just north of Gallipolis, Ohio) in 1953. The chain has grown to nearly 570 locations in 23 states, primarily in the Mid-Atlantic, Midwestern, and upper Southern states. All locations are corporately owned, not franchised.
