I was in NYC recently and stopped in at the frozen yogurt phenomena known as Pinkberry.  I didn’t realize there were so many opened/scheduled to be open.  I went to the one near Penn Station in K-Town, one block away from the H-Mart.  In typical fashion there were a lot of Koreans there, just saying.  I tried both the green tea one and the regular one.  I think the regular one is better, the green tea masks some of the sourness from the yogurt and as someone that eats 2-4 quarts of yogurt a week i like that sourness.  I think the perfect combination is the regular with raspberries (or another tart berry), there are some odd toppings like chocolate chips.  Overall it was nice and refreshing on a hot day, i think i paid $5 for the smallest serving (i think 5 oz?) and raspberries.  You pay about $1 for each additional topping, and the sizings go up to 12-13oz i think.  I wouldn’t go out of my way for it, but i liked it and the line was only about 10 minutes when i went.
