Some friends and I caught a show here over the weekend and we weren't disappointed. This was actually my first visit to the Rex, a decent smaller venue on the Sah Side.
Getting in was fairly easy...short line, ID check, will-call ticket pick-up, hand stamp and we were good to go. My one friend bought the first round of drinks at the small bar behind the entrance and I took care of the second round (PBR tall boys to mix in with the hipster crowd) from the busier bar at the back of the open auditorium. Prices were about what you'd expect.
Nothing fancy about the interior, but the sound was very good and the packed house, including us, had a great time. Too easy. 3.5 Stars.
