Been to this great venue twice, once for the tchaikovsky black swan Russian ballet, where we say upstairs on the second floor.
The second time was just earlier this year at a concert for an international singer.
The venue is beautiful and always clean, kept neat, with service representatives everywhere and ready to help.
My only recommendation if you're willing to visit, is to book your seat on the main floor, where the seating area is much better, more comfortable and way more leg room compared to the seats on the second floor.
I have been to other venues in Toronto and Mississauga, but this is definitely one of the best places in To.
