FrankiBerri Cafe, Ashburn

With 16 ice-cream and frozen yogurt flavors and more than 50 toppings, the dessert possibilities at FrankiBerri Cafe are virtually endless. Well, technically, they number 800 possible flavor combinations—but that's if you only got one topping. Fortunately, you can add as many toppings as you like and pay by the weight. Want to load up a cup of tart vanilla froyo with fresh strawberries, vanilla wafers, and fudge sauce, and top it all with whipped cream and chocolate shavings? Have at it.
