All the monorail CS options are pretty good.
Contempo Cafe is great overall - love the marinated beef flatbread, chicken caesar salad, turkey BLT, hot turkey sandwich, and roast beef sandwich. For breakfast, I love the bounty platter, as well as the waffles with banana and caramel.
I love the grilled chicken sandwich at Gasparilla's at GF. Also the fattoush salad is interesting. The problem with Gasparilla's is that it's literally in the same room as the arcade, so it's usually noisy. On the upside, you can see Cinderella Castle from most of the outside tables.
Captain Cook's has noodle bowls and some sandwiches/flatbreads. I like it most for the dole whips. It also has tonga toast for breakfast, but I think it's too heavy and sugary.
