I saw Famous Original Ray’s as fuel, in my non-touristic neighborhood (Turtle Bay in the east 40s). Not a destination, just a Tuesday night slice that cost a couple bucks in the mid 90s.
I don’t remember the name of the place with the deep dish. It would have been around 1992 that I ordered it.
Emmett’s has been around since 2013. Might check it out some day.
