U swirl is my least favorite of the frozen yogurt chains. I have been to this one and the one on charleston. The yogurt itself seems much less smooth to me than other places- like it hasn't been frozen properly and thus has ice crystals in it. Granted I have only been twice, but each time I got two flavors (4 total) and they were all like that. Maybe that is something some people enjoy, but I much prefer the smoother Menchies style yogurt.
The toppings- these seem to now be exactly the same at every yogurt place so since the yogurt itself is not as good I do not go back to u-swirl.
