Actually, there have been a few studies say that when people want to see a show, they'd rather go downtown to see it, as it is part of the whole experience.
Plus, have you BEEN to Yonge and 401 at Rush Hour? It takes 20 min. just to get off the freeway or into that North York Centre area.
I come from Richmond Hill and takes me the same time to get there, as it does downtown via DVParking Lot. Yes, Yonge is THAT BAD.
Also, I don't find parking any easier or cheaper in North York (granted, I know all the good spots downtown). And unless it's good Korean you want, there's really nothing around that area that I think is good (and no, Milestones is not good)
So I think that whole "Oh, North York Centre is a place to go" isn't actually a thing that happens for real.
And yah, I saw the show 3 times and it was always half empty (granted, half empty is still almost the same size as the NYC theatre so in fact, it didn't need to be full to be making the nut.)
