I like Cosmic Ray's for lunch, though if someone wants a sandwich while someone else wants a burger, you have to stand in two lines. And it's busy. Pecos Bill is also nice. The food at Columbia Harbour House does not appeal to me.
Never been to CHH but I keep meaning to ... it sounds so yummy!
We ate at Cosmic Rays on a MNSSHP night - food wasn't so great (only the burger line was open, and Disney CS is not known for its burgers lol) but the topping bar was outstanding!!!
I was previously a fan of Caseys (a sentimental must do), but the new buns have turned me off on that.
