We visited the Jazz Bar on Saturday night. We were originally scheduled to get there an hour before sunset. When we arrived at the Hancock building, we had to queue long after entering the elevator to the lounge. We arrived at the lounge and started another round of waiting to find the empty table. There was no empty table until after sunset, and we had a table in the room overlooking the water so the view was not very good. After sunset, the lounge is quickly cleaned up, so take your table with you if you want to go at night. Otherwise, I would definitely recommend giving yourself enough time so you can have a more decent table to enjoy the sunset and have views from the women's lounge.
