I think that TCBY has good yogurt and this particular location has great service, but the problem I find is that this TCBY seems to be always filled with idiots after 9 PM. I go there a lot, and always have to wait in a line of gaggling UT students that act like they are still in junior high school. Great place to go with the kids during the daytime, and fine just so long as you don't visit during the evenings.
Pros: good yogurt, amazing service, very clean
Cons: bad evening customers
