This place just opened a week ago in NoDa, right next to Crepe Cellar. I tried it Friday during the gallery crawl and it was awesome. I've had Activia before so I am not a stranger to active culture yogurt (or as they call it, tart yogurt) but Activia and the like have nothing on the real deal... it was fantastic! I had it with mango, fruity pebbles and granola. Next time I will leave off the granola, I think the sweetness of the mango balanced the tartness of the yogurt awesomely. I would also leave off the fruity pebbles, but Mrs. friek loves it.
Prices are quite reasonable ($3 for a small, $4 medium, $5 large) and include up to 3 toppings. We shared a medium and it was plenty for 2. The decor is very welcoming and comfy, they welcome dogs and have a small bench out front for when the weather isn't unbearably hot. They are also one of the greenest places I've ever been to, to include spoons made of 100% corn, fully biodegradable. Of the 20 available toppings, wherever possible they are locally sourced. The green link on their website has more details on this.
