Unfortunately, all of the dining options in AK, with the exception of Rain Forest Cafe are counter service. From what I understand, when Rain Forest signed in to have a restaurant at Animal Kingdom, it was in their contract that there would be a "no compete" clause... meaning that as long as the contract was intact, AK could have no other full service restaurants.
This may be why you are not happy with the selections at AK, but give Tusker House a try. For a counter service restaurant, the quality is on par with a full service restaurant, and it is quite a bit cheaper!
The list of counter service restaurants in AK include:
Flame Tree BBQ (crossroads to Africa/Dinoland/Asia)
Pizzafari (Africa)
Restaurantosaurus--- yes, it is a sit down meal... basically McDonalds, though ( Dinoland)
Tusker House (Africa)
All of the rest are snack shops and carts, that include:
Chip n Dales Cookie Cabin (Camp Mickey-Minnie)--cookies, ice cream sandwiches
Dawa Bar (Africa) - Beer and coctails
Harambe Fruit Market (Africa) --fresh fruit, joices and beverages
kusafiri Coffee Shop and Bakery (Africa)-- pastries, pretzels, caramel apples
Tamu Tamu Refreshments (Africa)-- ice cream, sundaies, floats
Anadapur Ice Cream-- (Asia) Ice cream and floats
Chakranadi Chicken Shop (Asia) -- Chicken satay, pot stickers and corn
Drinkwallah (Asia)-- beverages and trail mix
Upcountry Landing (Asia)-- beer and cocktails
Dino bite Snacks (Dinoland)-- ice cream, sundaes, floats
Dino Diner (Dinoland)-- Turkey legs, pastries, drinks
DinoLand Snacks (Dinoland)-- McDonald's French Fries
Hope this helps!
