I rank Riverbelle Terrace as one of the nicer counter service places at DL, but it's definitely just a counter service place. There is seating inside and outside. We just ate there last week! As I recall, there is a chicken salad, a fruit salad, a turkey sandwich, a salmon sandwich, and my favorite - clam chowder or vegetable stew in a bread bowl with a side salad. I always get the clam chowder. We also like the kids meal there because it's one thing our boys will actually eat - a peanut butter sandwich (with our without jelly) on white bread with a side of fruit or chips. They also have several desserts like chocolate cake, cheesecake, etc. The one difference from other CS places is that you get real plates and silverware. I can't imagine how many real forks and knives they have to fish out of the garbage each day.
The day we were there, we ate outside. Remy and Emile (from Ratatouille) came running by. Emile stopped at the garbage can next to us and started poking around. Remy and the handler had to pull him away. If you haven't seen the movie, Remy is the little gourmet rat. His brother, Emile, likes to eat garbage. It was really funny!
