The Musical version of Anne of Green Gables is good fun! We were expecting it to be cheesy and awful, but it come off very funny (cheesy in an endearing way might be the best way to describe it). My husband (who has never read Anne of Green Gables) even enjoyed himself! Definitely go and see it if you have the time and are a fan of AoGG. Its currently (Summer 2012) playing only on Mondays, Tuesdays and Wednesdays).
The Centre itself is in a very nice building right downtown, with a nice Restaurant/Bar and a very full gift shop. My only complaint about the theatre is that they have wildly different prices ($20-75), but all of the seats are pretty much the same. There are no aisles, so if you have a centre seat you have to climb over 30 odd people to sit down.
