Monk's Pub -
A great spot near the Loop for a post-work tipple, this cozy beer and burger joint also packs them in around lunchtime. It can get a little noisy during the rush, but you'll want to savor your meal anyways, so why talk? The bar food here is among the best in the city, especailly the burgers, which garner rave reviews. Not for the diet-conscious, obviously, but what can you do?
