I agree, Hot Doug's is a total no-brainer. It's a lot of food, but if you get a Chicago-style dog and one of his
daily specials, you get tradition and innovation in the same lunch. There are other establishments that are better for a Chicago-style dog, but his is more than respectable (though you'll want to do raw onions instead of the grilled he sometimes offers if you want to stick with tradition). For the specialty sausages, however, he's one-of-a-kind.
I also applaud the decision to have an Italian Beef. I absolutely wouldn't miss it and, frankly, I'd put it ahead of both a Chicago-style dog and deep dish in terms of importance when you're talking signature Chicago gutbusters. The downside is that the best establishments, IMHO, happen to be strewn around the outer reaches of the city, quite a ways from where you'll be staying. Devotees of Al's would disagree, however, so maybe that's a good place to hit. Even if the full depth of Al's allure is lost on me, many whose opinions I respect beg to differ, so I think that's a good choice, and fairly close to where you'll be staying. Plus, when it comes to grungy charm, Al's absolutely epitomizes the Chicago Italian Beef stand. Just be sure to hit the original on Taylor if you go that route. The quality of the satellite stores is dubious at best. Mr. Beef is also relatively close to where you'll be, and when they're on they're fantastic, but they've been so inconsistent as of late that I hesitate to recommend them. I'd hate for your first (and possibly only?) Italian Beef to be a bad sandwich, and recently they've been slinging a fair number of bad sandwiches. If you don't mind trekking a little further, Tore's is probably my favorite near the heart of the city and they're always on. One thing I would urge you to do is get the sandwich dipped. There are those who dig dry, but I'm of the opinion that an Italian Beef is just a sandwich until it's sopping wet, at which point it suddenly
makes sense. It's a mess, but that's a good thing.
Mexican has been covered as a can't miss, but the other one I'd urge as an
absolutely positively do not miss would be either TAC or Spoon Thai (not to be confused with Thai Spoon) for Thai. They're written about extensively on the board. Read up on some favorites and be sure to hit one of them.
