Cap'n cooks at the poly is a great CS option , easy to get to by monorail, the Aloha Pork Sandwich is FABULOUS, made with the same pork from the Luau, and you can get Dole Whip for Dessert!!
Also on the monorail as mentioned is the great Contempo Cafe, Delicious Cupcakes (Black forest, and Dolce de leche) The sandwiches are good be the Flat breads are AWESOME!
we too love WPE @ DTD, breakfast and dinner, great salmon, super breakfast pizza, cornflake french toast, and my new favorite this year, the terrific omelette, tomatoes, etc!
