We stayed there at Christmas. We didn't use room service, but did eat lunch at the pool bar one day. They had a good variety of sandwiches. I had a chicken caesar wrap (or something along those lines). It was very big and quite tasty.
Enjoy Bonnet Creek! I thought it was a great resort. With the kitchen, we stocked up on breakfast and lunch foods and usually ate dinner at the parks or Downtown Disney. Bonnet Creek is very close to lots of good food.
