Am planning to visit Chicago at some point in the foreseeable future and have done some research before posting here. Would appreciate suggestions or corrections as needed. While there, my goal will be to seek out some eateries that are easily reached with a home base area in The Loop or via a reasonable El ride -- will not have a car -- and would also be open after a full sightseeing day (no lunch-only spots unless they're quick and easily reached in a sightseeing itinerary). Specifically have interest in cuisines we're not strong in where I live (Eastern European and German especially), or things that are unique to Chicago or that this city does really well. Specifics follow.
-deep dish pizza or stuffed pizza. Poking around here suggests that the best options fitting the bill would include Gino's East (deep dish), Lou Malnati's (deep dish), Giordano's (stuffed), Pizzeria Uno (deep dish), and Pizzeria Due (deep dish). We have Uno's locally, so am thinking I'll concentrate on the first three.
-Italian beef sandwiches. Al's #1 Italian Beef and Mr. Beef, with the former having an edge around here.
-Chicago style hot dogs. There are some otherwise worthy options that apparently are either not accessible via public transport or have short lunch-style hours (Hot Doug's, Superdawg), so I'm passing on them. That leaves Portillo's and Gold Coast Dogs, perhaps Wiener's Circle, from what I've seen.
-Eastern European, German. Am thinking Red Apple Buffet (Polish, the one at 3121 N. Milwaukee is near the Belmont stop on the Blue Line) and Russian Tea Time (Russian) are good possibilities. Might have considered Berghoff (German), but there seem to be some questions about whether it's even open nowadays, and it appears to get minimal love on this board. In fact, no German places seem much liked here, from what I've seen.
Would very much appreciate any feedback, including other spots I'm missing here.
