There's a pretty good variety of vegan options here, and the prices aren't ridiculous, which is a plus (I've gotten used to paying $5+ for small cups of frozen yogurt and gelato and whatever else).
I tried their chocolate sorbetto and the hazelnut gelato. Both are vegan, though I found the chocolate to be bland and not creamy or chocolate-y enough. The hazelnut was slightly better (thicker, smoother), but also not great.
The combination of chocolate and hazelnut is divine, but in this particular incarnation it didn't come together for me. For $3.50 for a cup with both flavors, though, it's not a bad value at all.
