The simple act of inhaling at Billy’s probably adds calories to your diet—the air is that full of butter and sugar. The bakery specializes in cakes and cupcakes, but it also has cookies, brownies, and other treats. The place is cozily painted in pastels and decorated with a handful of vintage diner-style tables; the only edge in the place comes from the hipster-y staff. Warning: A slice of cake can feed two adults.
