MK Columbia Harbour House - Great sandwiches and DH and DS love the Clam Chowder. 2nd would be Peco Bill's - nice fixin's bar for the burgers.
EC We love to try the WS international CS choices. Our favorites are the Cantina in Mexico, The Sommerfest in Germany, the Tangerine Cafe in Morrocco, and the Fish and Chips in the UK
AK The best CS in all the World was the Tusker House, which they have changed into a buffet restaurant. The new menu does not appeal to me. We tried the Flame Tree in October and the consensus was it was just okay, not great. My turkey sandwich was awful. We would probably go back again. Haven't been since the Yak & Yeti opened.
MGM Nothing great, but the Backlot Express is the best of the choices, IMHO.
