As I just said in the Fan Gatherings section -- try The Queen Elizabeth. If no one else knows for sure I'd say it's the best bet. It's the perfect location for them, it's a Fairmont, which means beautiful and old, and it's got great food.
True, the W is probably a really good bet too -- yeah, that's better than the QE. Perhaps what I meant was more reputationally fancy than the actual building or rooms.
