We went to a centennial tea - it's the 100th anniversary of the Fairmont hotel chain, and they had a special tea for $19.07.
The tea itself was not great - sandwiches were a bit stale, the pastries were nothing special except the chocolate mousse cake, the crumpets tasted like the ones you get at the grocery store. Most annoyingly, they serve 8 tiny sandwiches for the three of us - kind of hard to divide up. Parties of two got three sandwiches each, but we were assured that it was standard procedure to give 8 sandwiches for parties of three. So you are penalized for having a larger party? Weird. These are tiny, tiny sandwiches on about a quarter piece of bread.
If you are thinking of going to tea at the Royal York, make sure to read this review first. (clue, if you must go, only go in pairs!)
Centennial Tea at the Royal York in Toronto
As part of the tea you get a tour of the herb gardens on top of the hotel. They are not open to the general public. This was the part that I liked best.
The gardens were impressive, but mostly I just enjoyed being up there and the view.
