Frisch's Mainliner Big Boy Museum

Sadly the Mainliner is closed indefinitely. The historic sign was salvaged and may be at the sign museum.

Frisch's Mainliner Big Boy Museum

Small, new museum display in the middle of a bustling, functioning restaurant. Gives a brief history of Frisch's Big Boy and a rundown of the Big Boy logo through the years. There is a Big Boy photo op and a small case of memorabilia. We had to tell the hostess we were only there for the museum and not to eat, which was awkward.

There are restored Mainliner signs in the parking lot.
