First timer to Chicago, but a buddy took me to Benchmark and ended up having such a good time, I went back later in my trip! The weather was nice, so they retracted the rooftop which was cool. They had one of those sound systems that was synced with the video playing on the flat screens, not bad. A variety of drinks on tap and in bottles, two levels and a descent crowd.
Didn't expect to have to wait in such a long line, but it went at a descent pace. Seems like a good place to watch some games. Wasn't particularly fond of the food, wouldn't go there to eat.
Had a little outdoor area that was cool (in front of the entrance).
