Chicago
The Green Door Restaurant & Speakeasy
The Green Door has been on Orleans Street since 1921, when it operated as Huron-Orleans Restaurant and quietly supplied drinks during Prohibition out of the basement. The green door out front wasn't decoration: it signaled to locals that the police had been paid and the coast was clear.
The main floor functions as a classic Chicago tavern with the sort of accumulated decor that only comes from a century of operation: vintage signs, old photographs, and objects that were probably hung up and never taken down. The food is solid, the chicken strips in particular get mentioned often. It's a neighborhood bar that happens to be over a hundred years old and looks exactly like it.
