Madison has been slow to get on the frozen yogurt popularity train...however, it also didn't do the fad the justice it deserves.
On the west coast, you can find frozen yogurt places everywhere, and a lot of them are self-serve and you pay by the weight.
At Red Mango, you pay waaaay too much for a simple dessert. Just because their chocolate chips are Ghirardelli does NOT justify the price of their frozen treats.
I do appreciate the variety of toppings they offer, particularly mango, which is not too common around here.
They offer samples, which is always appreciated, and have special flavors which keeps the menu exciting.
On the whole, its pretty good - but the "pretty" is pretty much only because they don't really have any competition in the "fancy" frozen yogurt area.
