Sweetlix has the advantage of being the only frozen yogurt place downtown, but frankly I'd be willing to travel to any of the other Razzy Fresh locations instead if I really needed some fro-yo.
The atmosphere inside is sort of like a 12 year old girl's bedroom, but less cozy. There also aren't any chairs inside, making eating your yogurt there slightly awkward. But the biggest problem is that this place just isn't all that good. There are only a few flavors, and since they sell their yogurt by size and not by ounce, getting toppings can be a bit tricky. They'll fill your medium cup and then there won't be room for the strawberries and brownie bites that you want on top. When we went most of our toppings ended up on the counter. Very disappointing. Plus it was just a little bit too pricy for what they give you.
Overall, avoid if possible. Go get some soft-serve instead.
