We loved Mythos in Islands of Adventure! We can't wait to go back!
The atmosphere is so unique, it's unbeatable (especially for a mythology nerd like myself). And the food was wonderful! I'm always a bit of a picky eater, but my husband talked me into trying sushi for the first time while we were there and I couldn't stop eating it. Also, the prices are pretty decent and you get a lot of food for the money. We shared an entree and were totally full.
I honestly can't say enough good things about this place.
