The ACC is a great arena to watch anything from concerts to hockey games and basketball games. Almost every seat in the ACC has good views and the arena can hold much more than the old Maple Leaf Gardens could.
The building is situated in the busy area of downtown by the Gardener expressway in Toronto. If you're looking to get here by car, think again. The traffic by the Gardiner is horrendous on a regular work day and ten times worse on game night. If you happen to catch a game, try and take the TTC instead. The walk from Union station is super close and will save you lots of time and money on parking.
The arena also serves decent food, although like any arena everything is overpriced and expensive. Look forward to paying $12 for a beer and $15-20 for a small fast food meal on game night. I'll always come back here for Leafs games even if they always disappoint me!
