Anyone who loves/crave Pinkberry fro yo may find an acceptable substitute in the Landmark Center. In the place that was formerly "KnowFat" and is now "UGrill" (next to the movie theatre entrance) there is a counter that serves just frozen yogurt.
I ate half a swirl (they have plain and raspberry as their two flavors). It has the same general tang as Pinkberry. It's also set up with toppings of fresh fruit and granola, (though not with nearly as many as Pinkberry -- also, NO CEREAL toppings). We had raspberries added to ours and the server opened a package of Driscoll's raspberries right in front of us, washed them, and put them on our fro yo. Toppings are $1 for the first, $.50 for each additional.
The prices aren't nearly as bad as Pinkberry either. Our small (4oz) was $2.50; with the topping it came to $3.86 with tax. The 8oz was $3.50 (if I remember correctly).
If you love Pinkberry and want in on this action, better go check it out. I have no idea if this place will survive, given that ice cream season is winding down, and the outlet's proximity to Cold Stone, Emack, etc.
