9. There’s a Hidden Art Supply Store Inside

On the first floor of the Arts Students League building is a tiny but well-stocked art supply store, a true hidden gem known primarily just to students and art insiders. There is no sign on the outside of the building to denote its existence. But despite its small footprint, the store is wildly successful. According to Ken Park, “Art supply reps tell us that the League’s Art Supply Store sells more products per square foot than any other store they know. We carry more than a thousand kinds and colors of professional grade paint.”
