We LOVED Yak & Yeti when we were there in September. We don't like Rainforest in Chicago and won't even bother with the one in Florida. We've not tried Tusker House. Here is a link to my review of Yak & Yeti: http://www.disboards.com/showthread.php?t=1952509 (it is near bottom of page 1)
I should add that my daughter is on the gluten free/casein free diet, so I am a bit worried about Yak & Yeti for that. Anyone know how well they handle this type of thing???
We tried Yak and Yeti a couple of weeks ago. We didn't expect it to be good, and simply went out of desperation as we were hungry. We were pleasantly surprised. Everything we had was tasty. Also, the portions were generous, which worked well for sharing.
We are big Tusker House fans, it's a must do on every trip for breakfast (so fun with the safari characters!) and dinner, too. The buffet choices are a wide variety that covers all tastes, including children, but we enjoy the different food that we don't normally get a chance to eat.
Another vote for Yak & Yeti. Had an excellent lunch there in Sept. You may want to get their main number from the dining line and contact them directly with any questions as far as the gluten issue.
