I'm a bit of a traditionalist in a sense, so my review might be a bit bias as I loved going to Maple Leafs Gardens back in the day (the one exception being that the guys bathroom at the gardens was a round splash pad pond, and being a youngster I was a little intimidated at times!).
But time moves on, and so should I. Having been the son of a season ticket holder for more than 25 years, I have gone to a fair share of games (well except for the ones where I scalped the tickets to go out partying with my friends when I was younger!). The arena itself is a modern day amphitheatre with exceptional seating in most sections. The section I love the most is the 317 or 318 and as close as possible to the rail. Other great sections are the Blues or the Gondola. The problem is that you can rarely get tickets for Leafs. But Raptors games are pretty easy to get a hold of. The facility itself has all the amenities, private suites, overpriced restaurants - except for Tim's as they have to keep their pricing standard as per company policy. Overall you better has some cash to spend when you get here for the Leafs, Raptors or a Concert.
Overall the facility suits its purpose.
