Stonemill Matcha shared by @eater says: ""This is San Francisco’s first premium matcha cafe — a space wholly devoted to matcha, with top-notch tea available hand whisked, sparkling, with milk, or over ice cream. It’s also infused into all sorts of treats, including matcha cream puffs, matcha croissants, and matcha cream pies — some of which are the result of a collaboration with Tartine Bakery."" on Postcard
