It's connected right to the Air Canada Centre making it a convenient spot to get a drink or meal before or after an event. Plus like others have mentioned, they have a MASSIVE television wall that is only really viewable when you go to the upper levels.
Other than that, the place is very loud, finding a table will be hard unless you call ahead, and as always the food/beer are ridiculously overpriced.
Nice to visit once, but you're better off going to a smaller establishment.
