Frequently touted as the best cookies in NYC, this is one of the few times I'll go along with the crowd. These cookies are insane. Levain is one of the few places I will wait in line because the cookies are that good. I'm partial to the dark chocolate chocolate chip, which is rich with only a touch of sweetness, crispy edges with a chewy center and chocolate chips that are practically creamy even when eating fully room temperature. The classic chocolate chip walnut is a perennial favorite as well. But quite honestly, after waiting in the quick moving, but very long line, you might as well go all out and get all four types of cookies, including oatmeal raisin and dark chocolate peanut butter chip. You won't regret it (though find someone to share - these are really big cookies).
