Nothing beats going to the symphony to hear absolutely amazing music performed by an extremely talented group of individuals.
You will have a good view of the stage no matter where you sit. I've been to over a dozen shows here are have always sat in different spots.
The only seats I didn't like were the ones that were too close to the stage. You just can't see anything.
The mezzanine is my favourite place to sit for a nice birds eye view of the orchestra.
Also, if you're under 35, then you should sign up for TSO Sound Check will allows you to buy tickets for approximately $16.
The sounds in this place is fantastic. They really did a great job on the acoustics. Much better than the Four Seasons and obviously a much larger orchestra.
The drink menu is expensive but everything else about this place is top notch. Highly recommended.
