9/5/15 Update: Menu updated.
Storybook Circus Pretzels and Popcorn are located out in front of Dumbo on the walkway in and out of the Circus area of Fantasyland.
It offers a pretty generic menu similar to what’s available over at the Pretzel Cart in Frontierland.
Mickey Pretzels are about what you can expect, Soft, chewy, and salty, just like their counterparts that look like pretzels. I highly recommend the cheese sauce.
The Churros are also the same as you’ll find around property. It’s fried dough-pastry coated in sugar. I like Disney’s because they’re a nice mix of soft and crunchy. Both items are filling snacks.
If you’d like to sit, there are a ton of tables in the back of Storybook Circus and plenty of ledges to sit on.
