U-Swirl is my favorite frozen yogurt place hands down. Now that they've added Rocky Mountain Chocolates to this location, it is sweet overload. Staff is friendly and helpful, There is a nice variety of yogurt, and you can request sample cups. The toppings are always fresh with a nice selection of choices. Mochi toppings are my favorite.
