Adorable little brightly colored shop with adorable helpful staff.
The froyo is a serviceable snack if you don't mind the flavors tasting highly artificial. There's a fruit-punch-ish flavor (maybe it's strawberry lemonade?) where the fake sweet-tart edge works really well and is part of the charm; but on coconut flavor, I'd ordinarily expect less harsh and more mellow.
The toppings bar is the shortest I've seen, ever, and I've seen a lot of froyo. It covers the basics.
Basically, if you're on Mill Avenue and either semi-drunk or feeling dehydrated beneath the relentless Arizona sun -- and that covers 90% of everybody there -- this will, on balance, improve your condition.
