We are leaving for our first visit on Wednesday, so I'm not speaking from experience (except, loved the Dole Whip at WDW), but here are some I plan on trying to try . . .
Bengal BBQ - has Mickey shaped pretzals
Golden Horseshoe - chili in a bread bowl
Mint Julip Bar
(CA) Golden Vines (name?) - wine tasting flights for $10
(CA) Bakers Field Bakery - coffee frappe'
(CA) Taste Pilots Grill - good burgers & has toppings bar - I think??)
(GCH) Whitewater Snacks - nachos
Have fun!
