We went there to watch Shen Yun. It is a great theater overall. Big seating capacity and the acoustics are very well designed to give an amazing experience. However, the height adjustment between the two rows could have been a little more. This is a good place for dance shows and music concerts etc but not for plays. Small theaters are the best for that. The tickets are quite expensive - especially in case of Shen Yun, we found it overpriced, but then that's the case with most of the theaters where the price is based on the quality of the venue rather than the quality of the show.
They have a coat check and washrooms one floor below. Not too sure about the parking since we just took an Uber. However, plenty of taxis and Ubers available around this area.
