As a rule of thumb, the resort CS locations always have more entree choices than the parks. And they have more things for dinner than for lunch. You don't need to be a resort guest to take Disney tranport to/from any park to a resort. POR has a great build-your-own pasta at dinnertime. Pepper Mkt in CSR is pretty unique with some big meal options; it's almost a cross between a CS and a TS location. You DO have to tip, but you are escorted to your own table and your server brings your beverages and refills, and clears the table afterwards.
MK - take the monorail to any of the 3 resorts and eat there. Contempo Cafe in the CR is fun because you eat with the monorail going by overhead. At Capt Cooks in the Poly (downstairs in the main building) they have some great Polynesian flavors (love the pulled pork sandwich on sweet bread) plus Dole Whip soft-serve is one of the dessert choices.
AK - Flame Tree has good BBQ ribs and chicken, including a very refreshing salad with BBQ chicken mixed in. Yak&Yeti CS has some decent asian options.
HS - I particulary like Starring Rolls Cafe. It's on the main street, tucked into the corner by HBD and the street leading to ToT. Wonderful sandwiches plus bakery items including the famous Butterfinger and Red Velvet cupcakes for your dessert choices.
Epcot - really, except for Electric Umbrella (yuck!) you can't go wrong. Just about every country in the WS has a CS meal location and some of them are better than the TS options. Or if you're in the front of the park in FW, as several others have mentioned, Sunshine Seasons is a nice food court in the downstairs area of The Land.
