Assuming lunch, since you just cancelled lunch

.
MK: Liberty Tree Tavern and The Plaza - both are relatively simple (though I enjoy the atmosphere in LTT) and have "easy" menus. Neither are very good value on the dining plans, but with Dx, you can get that covered elsewhere. (Note: I have no interest in the dinner menu at LTT, not a fan of Thanksgiving-style meals in general since I'm picky and don't eat cranberries, or turkey, or chicken, or fish... so your mileage may (and likely will!) vary)
EP: San Angel Inn - Hands down. Menu is a bit more difficult than you may expect, since it's much more authentic Mexican than you'd see at a local Tex-Mex type of place. It's very good though and you can't beat the atmosphere. (Note: I typically prefer the lunch menu to the dinner menu here as well).
DHS: Mama Melrose is the only place that I eat here, though Brown Derby may fit the bill as well. MM isn't anything special, but it's the best of a short list. '50s isn't bad either, but I don't really enjoy the antics. I'm a party pooper like that.
Resorts: Sanaa over at AKL-Kidani is my favorite restaurant of last trip, followed closely by Grand Floridian Cafe at the Poly (JK, it's at Grand Floridian

). Sanaa has a great atmosphere, very tasty food, and great service. GFC is conveniently located to MK and has a nice simple menu, but was very good when I was there for dinner last year. Kona Cafe at the Poly (yes, this is actually at the Poly, not like where I lied about GFC above) is also quite good and I usually make an effort to grab both breakfast and dinner there on each trip.
