I have not been to the Tusker house, so I cannot really compare, but....
Flame Tree was dh's favorite meal of our entire trip last Feb, including all the nice TS restaurants we ate at! We are going back in March and he has requested to eat there again. It is probably the only restaurant we will repeat besides a few character meals for the kiddos. He thought the ribs were some of the best he has had. He is a real "foodie", so I thought it was pretty funny that a CS meal kept him happy!
