I love sweet frog and this location is always very clean and has super friendly staff. They seem to change flavors- at least 6 of them- monthly so you're always in for a surprise. My favorite seasonal froyo has been the cheesecake and pumpkin. Plus, if you can't decide, ask a staff member and they will give you a free sample of any flavor.
In addition to the vast flavors, they have an extensive topping bar with almost everything you can dream of- fruit, nuts, cereal, candy and chocolate. Plus they have caramel, chocolate, strawberry, marshmallow and peanut butter sauce!
Now let me go die in froyo heaven.......
