I dug around in the Chicago Area Board and found (in one of those "Help me! I'm from out-of-town and I don't know where to eat" threads) some positive comments about Erwin at 2925 N. Halsted.
4 of us (2 from Milwaukee, 2 from Montana) met there for dinner Sunday night. We liked the food, the staff, the place, the clientele, the bar snacks, the neighborhood, the bar snacks...well, you get the picture.
Thanks for a great recommendation.
