I know most people will say Flame Tree, but I really like Tamu Tamu Refreshments. Its across from Tusker House. They only have burgers, but they are really good, and if you're on the meal plan you can get a chocolate or vanilla shake for desert. If you go around back there is a very nice courtyard with tables that is kind of secluded and has plenty of shade.
Another vote for Flame Tree. (Though my daughter always finds it morbidly ironic that I gnaw away on rib bones while in a park where the theme is to observe, honor and celebrate all things animal!) "Dad. Can't just once you order a salad?"
We love Yak & Yeti CS, plenty of food, but if you want beautiful and cool indoors, Pizzafari is beautiful inside and if you don't like pizza, the Hot Italian sandwich or the Chicken Ceasar are great options!
Flame Tree is cool for food and theming. There is a great table in the corner that has a wonderful view of the Jammin' Jungle Parade! Yak and Yeti counter service has decent Lo Mein options.
I like the Yak & Yeti (Anandupur Local Cafes) CS...the Honey Chicken is my favorite, but I noticed they added a Sweet & Sour Chicken option, so I might have to try it on my next trip.
