Levain Bakery doesn't serve "cookies." No, that would be too simple... trite, even. Instead, they sell loaf-sized emulsions of chocolate, butter, and joy. With their crunchy, golden exteriors and unbelievably dense, doughy interiors, sinking your teeth into one of these will make your eyes roll right past the bliss point as you instinctively reach out for the nearest insulin syringe. For anyone attempting to adhere to a diet, going to Levain Bakery is the "cheat day" equivalent of committing adultery multiple times, abandoning your family, and refusing to pay child support. Highly recommended.
