That was my thing too. I assume they are somewhere in the Bay Area, although for the most part it seems falafel and schawarma are much more popular. But after living in Chicago for a year, a place that has the best hotdogs/burgers/gyros of ANYWHERE, I just figured it wasn't worth my time.
yeah, gyros isn't a greek thing, its a chicago thing. what you get in Greece is totally different. but the chicago version is pretty fucking great, anyway.
