Located at the "Hydraulic Hearth" restaurant on Swan Street, "(716) GAL-LERY" bills itself as Buffalo's smallest art gallery. It's a repurposed 1950s-era phone booth where works from a local artist are displayed. Pick up the phone and it plays a recording that tells you a bit about the artist and his or her work. There's also a "gift shop" that consists of a 50-cent vending machine that dispenses stickers and temporary tattoos designed by local artists.
