The Postcard opened on March 6, 2025 in the Buckhead space that previously housed Wave 3 Coffee — a fitting inheritance, since the cafe sources its matcha from Wave 3's premium line, including the earliest hand-picked, shade-grown harvests that don't make it into any supermarket tin. Owner Daniel Son built the room around the idea that a matcha cafe can be a design object as much as a tea counter, and the result is the most intentional matcha-specialist space intown.
The menu leans into cultivar work the rest of the city hasn't attempted. Expect a handful of straight ceremonial pours alongside composed lattes that treat matcha as a base rather than a flavor additive — blueberry lavender, strawberry rose vanilla, coconut water mango, and a strawberry yuzu matcha tonic that has become the warm-weather order. Syrups are in-house; the pour is attentive. If you're coming in matcha-curious, ask for a straight bowl first and use the lattes as the second cup.
The room itself is small — about 700 square feet — and the fit-out tells you what the project is about. Curated postcards, books, and magazines on design and urbanism line the walls; the seating is built for a slow sit with a single drink rather than a laptop-and-lunch stretch. It's the closest Atlanta has come to a Kyoto-style specialty-matcha cafe and the Buckhead counterpart to Matcha Cafe Maiko's Buford Highway storefront — different vibe, same level of seriousness about the leaf.
Practical notes: Walk-ins only. Peachtree Road street-front with shopping-plaza parking nearby. Weekend openings run an hour later than weekdays — plan around 8am if you want a quiet Saturday bowl.
