Here’s a quiz of Chicago slang. I took it although only went there to visit a cousin once in awhile or to dinner with friends as a teen. Somehow I got 100 % but had to guess on a bunch of them as some were places I wasn’t familiar with or deep back in memory had me guess right but still thought it couldn’t be. I guessed no relish on hot dogs is that right? Apparently it was.
