#21 Cuban Burger
An omage to where Burger 21 began, Tampa, FL. Our house-made mojo seasoned pork patty sits a top our mustard based sauce, on a bed of pickles and a slice of Swiss cheese. The patty is then topped with grilled ham and salami, more Swiss cheese and drizzled with our signature 21 sauce for a reinvented version of a classic sandwich.
Cinnamon Bun Shake
A rich blend of vanilla ice cream, walnuts and cinnamon
maple sprinkle. Topped with a delightful house-made
cinnamon swirl for dunking. Yum!
