Came to see what the big deal was about. We arrived on a weekday around 4pm and the wait was about 45min (30min outside, 15min inside), pretty decent weather so we didn't mind the wait that much, though it's a bit stuffy indoors since they do not have AC.
We got the cheesecake and also tried the madeleines. The cheesecake was very fluffy and eggy, and of course straight out of the oven. It wasn't my cup of tea though - I prefer sweeter desserts, and this just tasted like a very lightly sweetened cake. The madeleines (which are made with honey) just tasted like soft cupcakes.
We did not mind the wait but I don't think I'd come again unless the wait was less than 15 min. It is ridiculous that people wait more than an hour for this.
On a positive note, they just bought out the space beside the current location, probably to expand the current space. Hopefully they will make the cakes at a faster pace than the current 12 cakes per 15 min. There is no seating but one can just go into the Eaton Centre food court if they'd like to eat it right away sitting down.
