Just like Marble Slab, Austin-based Amy's lets you mix it up. My personal favorite is The Montrose: sweet cream mixed with bananas, fluffy marshmallows and -- naturally -- rainbow jimmies.
The Mexican vanilla is also a long-time favorite, but rotating and/or seasonal flavors such as Shiner Bock, Belgian Blueberry and Bourbon Chocolate Walnut keep patrons coming back each week to see what's new.
8. Pollo Bravo
The Pollo Bravo on Richmond at the Beltway is the only place in town I know of that makes homemade lúcuma ice cream. In fact, they're still the only place I know that serves lúcuma ice cream, for that matter.
The flavor is difficult to describe -- caramel custard or flan with a telltale chalkiness at the end -- and in its native Peru, lúcuma is the preferred ice cream flavor over any other.
