At Peach Swirl, you might see mixed berries and hunks of Snickers cascading down a mound of frozen yogurt in a cup. And that's just one of the seemingly infinite custom treats visitors here might make. In the back of the brightly-colored shop, it's easy to fill your cup with ribbons of any fro-yo you like from the self-serve machines. Whether you swirl together two flavors or choose single options such as non-fat cheesecake or low-fat cookies and cream, your cup is your personal dessert canvas. After that, head to the toppings bar—which is stocked with freshly-cut fruit, crushed candies, and sprinkles—where you can top off your custom treat.
