Just saw Postmodern Jukebox at this venue and it was great for the most part!
Location: Excellent! There's parking all around and it is relatively priced. There's a Green P just down the street at Queen and it's only $6 (at the time of posting). That is probably the cheapest parking I've paid in a long time when seeing a show. It is also close to the mall and restaurants so you can also kill time if you are in the area early. It's very hectic outside because the box office is right there an there isn't much room on the sidewalk.
Staff: I think they were pretty attentive and very welcoming. They were very polite and were great at communicating to get people to their seats in a cordial manner. They also got people in nice and quick, almost no wait!
Venue: If you want merchandise, good luck. There is only one location and it is downstairs where the washrooms are; essentially there is a huge congestion in that area. For this event there was only one girl selling the merchandise and I felt kind of bad since there was no organization and everyone was swarming her. Inside the auditorium, everything was pretty good. We were on the right balcony and the seats were cushioned (I think if you are in the top section they aren't). There isn't much leg space, but the chairs can slide forward/back so it worked out for me even though I'm pretty tall. I will say that I wished people in the front rows would lean back because it makes it near impossible to see stage left from where I sat when everyone decided to lean forward; but most of the stage is clearly visible and I could clearly see the performer's faces. The sound is amazing, and it wasn't too loud or too much echo.
Overall, due to the sound and the view I say it was great venue! I wouldn't mind coming back but I may have to move up a row or two to avoid those people who lean forward.
