The Smorgasburg Snack Bar opened inside Whole Foods Bowery this week. Walk to the second floor, pass the line of people waiting for tossed salads, and head straight for dessert. There are slushies from Kelvin Natural Slush, nut milks from OMilk (I'm partial to masala chai cashew milk), donuts from Dough, and pie! S'mores Pie ($4.50) to be exact. They're baked by the girls of Butter & Scotch, and the slices feature graham cracker crust and a torched, gooey top of marshmallow fluff. Get all three components in one bite for maximum satisfaction; that dense and creamy chocolate ganache is no slouch.
