I've never had a bad time at the rex. The drinks at the bar are pretty pricey here. It's non-smoking, now, which is actually good. Whether there are chairs set up or it's SRO, the shows fill up and it's not TOO crowded to enjoy it. They usually have an interesting array of bands that come through, a lot of good jazz. Definately a place to check out if you're new or visiting pittsburgh.
