Mythos, best place in the parks. Mels is okay. Emerils in Citywalk was awesome, but Choup Chop in Royal Pacific Hotel was a little over rated. Remember there are two Emeril resturants at UO. My favorite, hands down, is Mama Dellas over at the Portofino Bay hotel. Awwww....the staff is unbelievable. The food is moderately priced, but it is well worth it. Reservations arent needed, but suggested. They have 5 different themed rooms, or is it 4? Anyway, they have them. And usually a guy walking around singing old italian songs, he is awesome.
As far as everything else...well, they're okay. Mostly the same kind of fare, hamburgers, fries. Latin Quarter is very good. Pat O'Briens has awesome food, and live entertainment after 4, i think. Fun joint. Margaritaville is way over-rated, and the line is always long.
