MK - Cosmic Rays, Columbia Harbour House
Epcot - Sunshine Seasons, Tangerine Cafe (open air), Boulangerie Patissiere
AK - Pizzafari, Yak and Yeti
DHS - the area near ToT and RnRRC offered a wide selection. Aside from the cupcakes at Starring Rolls, I did not like the CS/QS offered at DHS. If time allows, you might be better going to Epcot (or the Boardwalk) and having a look there.
