Momo Cafe is the daylight half of Momonoki — the Japanese-inspired restaurant on 8th Street that opened a two-story cafe wing with its own counter, seating, and identity. The cafe occupies the ground floor and a mezzanine that overlooks the I-75/85 exchange a block away; Japanese-minimal in the way the best Tokyo neighborhood cafes are, with enough seating to actually settle in with a laptop.
The matcha program is the reason this place belongs on a tea directory. Momo Cafe pulls its matcha from Marukyu Koyamaen — the Uji, Kyoto producer that has been making imperial-grade matcha for generations and is the gold standard for serious cafes. Drinks include a ceremonial matcha, an iced strawberry matcha that's become the signature Instagram order, and a black sesame latte that often gets paired with a matcha pastry. On the food side, the bakery program is in-house and the matcha croissant — laminated and green through — is what regulars treat as their weekly breakfast. There are six brewed teas on the menu: three sourced from Japan, three from Taiwan.
If you're trying to understand where Atlanta's matcha trend actually has depth, this is one of three or four intown cafes doing the real work.
Practical notes: Mornings are the quiet window. Weekend brunch stacks up fast. The cafe shares an address with Momonoki proper, so if you're meeting someone, say "Momo Cafe" specifically — the ramen side of the operation has its own counter upstairs.
