It took me a minute to decide if I was going to give this 4 stars or 5 stars. I was unfairly comparing Yogurtini with Yogurtology, my hands-down favorite yogurt place in town. But I don't think comparing the two is a sound way to rate this shop.
So 5 stars it is.
Yogurtini is spotless, and always has excellent flavors available. Their plain Tart is great, and I love their mint and peanut butter flavors. They offer a large selection of toppings. There is no hot fudge, but they have lots of good fresh fruit.
The actual FroYo flavors are very yummy- no weird chemical, fake tastes.
You can assemble your FroYo in a healthy, no guilt way- select a lower cal yogurt, top sparingly or load with fruit; or go whole hog and load it down with gooey sugary yumminess.
Employees are pleasant. If you need to sample, go up front and grab a few sample cups from the area by the register.
