also, if you guys are in Chicago and want to have some good steak, check out David Burke's primehouse. I think it's relatively new (maybe less than 5 years), but the place has some fucking tasty steaks. It's in the lobby of a hotel downtown, but they have a room where the walls are made out of some fancy salts where they dry age the steaks. Not sure if it's a gimmick or real (maybe cheftim can chime in), but they swear that it dries the steaks better.
Either way, tasted damn nice.
Also, Ruth's Chris is nice. I realize it's a chain, but you can't go wrong with a filet swimming in butter.
