We go here a lot since we live nearby. It's ok, but I have been to froyo places that were much, much better.
On their website they claim to have fresh fruits in their restaurants - 14 to be exact. I don't recall ever seeing this much fruit, and when they do have fruit it's almost always from a can (which means added sugar - not healthy at all!). If there has been any fruit it's strawberries (can't tell if fresh or not) and maybe canned pineapple.
They're not consistent in providing nutrition information on each of their flavors. When we went the first time each flavor had calories, fat, and sugar labelled (and weight watcher points, but WW has changed it's program recently so I'm not sure how accurate those are). Most of the time though only about half do, and the rest of the flavors are labelled with hand written signs without nutrition information.
The staff has always been pleasant during our brief interactions with them.
