Froyo makes me happy. I haven't been to many places, so I can't really compare Yogurtology to the other local spots. As most reviewers have said, this place is clean. They are always out with the mini vacuum sucking up the spilled toppings. We've been here a few times. Both when the place was empty and when crowded. But it seems to move quickly and there's never a long wait. I usually choose the sweet yogurts because the selections sound so good, but every time I realize that I do like the tart flavors better. There is always a No Sugar Added selection, which is a plus. The raspberry is awesome! The toppings bar has a great selection. I even witnessed another customer ask for something that was not out, and the employee went into the back room and brought out a cup of the topping for her. I especially like the MAYO!  The staff has always been friendly, greeting guests as they walk in and offering samples if desired. It can be a little pricey, compared to other shops I've seen, but for the convenience, quality, and once-in-a-while treat, it's well worth it.
