This is, hands down, my favourite frozen yoghurt in the city (and I have considerable experience "taste testing" establishments in and around town). The yoghurt itself is of the highest quality. It's not terribly sweet, but rather has a tangy, tart-like taste that makes it extra refreshing and a perfect base for the wide range of interesting toppings - and flavour combos - available.
I also love the fact that they have a sign on the register that says something along the lines of, "No need to tip. We believe in paying our employees a fair wage." I really think it speaks volumes about the owner(s) and the ethics of the place.
