Time Out says
Screw “venti” and “tall.” PS Gourmet has two sizes: small, and “the bucket.” This charmingly unpretentious South Boston haunt has tasty iced coffee selections, featuring such flavor infusions as Snickerdoodle and Chocolate Caramel Kiss. The popular PS Special is a cinnamon-dusted hazelnut mocha. It's family-run (and cash-only), but don't starting talking about “indie” around this townie crowd. Even as its reputation has grown, PS Gourmet has still maintained a neighborhood feel.
