Yogurtini - Just swirl it, top it, weight it, pay it
One of the very few yogurt places open until midnight, helps if you plan on grabbing a late night dessert. You've got a huge assortment of flavors to choose from. To add icing on the cake (well suits the context here) all yogurts are fat free. Furnish your yogurt with their huge assortment of toppings (berries, wafers, chocolate chips, butter finger, reese..)
Watch out for the weight, as the yogurt itself isn't cheap and you are charged based on weight (including toppings).
