The Big Downtown Restaurant
I really like the Big Downtown as a bar. It's one of the few places in the loop that you can go after work to meet a few friends and have a drink and an appetizer. In the early evening there is a pretty good mix of locals and tourists.
They have excellent drink specials and a lively atmosphere. There is sometimes live music, which is usually good, but often makes it too loud to really talk.
The food is fine, nothing special.
