If you find yourself really hungry in between meals but are a cheap motherf**ker like me, you probably don't want to spend any money on a snack. No munchies in your pantry and no billz in the wallet? No worries! Take a stroll up 2nd Avenue(between 75th & 85th streets) and stop for a free sample in every yogurt shop along the way. These delightful lil shops are plentiful along this strip, so if you hit all of them, you end up with the same amount of frozen yogurt in your belly as the fool who pays full price for a whole one. Plus, all that walking is probably enough exercise to come out from the calorie battle about even.
Make sure to try the "birthday cake" flavor from Pinkberry. It's fantastical.
