Chef J. Trent Harris — a James Beard Award finalist best known for the minimalist, omakase-driven Mujō — has quietly opened Koshu Club in Buckhead, and in its first week the room is already reshaping conversations about high-end Japanese cooking in Atlanta. The new restaurant takes Harris’s razor-sharp technique into a more social, grill-forward format where charcoal, sake pairings and vegetable-driven dishes share the spotlight with premium beef.
Koshu Club is the latest concept from Castellucci Hospitality Group, the team behind Cooks & Soldiers and Iberian Pig. The space trades the hush and ritual of an omakase counter for a dim, buzzy dining room anchored by a glowing bar and a soundtrack tuned to keep energy up without drowning out conversation.
What matters now is how Koshu Club positions luxury Japanese ingredients in a more approachable, communal setting — a move that could broaden where and how Atlantans experience top-tier wagyu and curated sake, while adding a new destination to Buckhead’s competitive dining scene.

Menu and approach
The cooking centers on direct heat and precise seasoning. Skewers and a binchotan grill produce smoky, focused flavors that let single ingredients carry the dish, while vegetable preparations receive as much attention and layering as the proteins. Service includes a dedicated team of sommeliers who steer sake, wine and cocktail pairings.
What to order
- A5 Kagoshima wagyu, 4 oz — $90: Served rare and finished over charcoal; sauces are part of the experience, with a citrusy daidai ponzu cutting through the beef’s richness.
- Nasu agebitashi — $16: Japanese eggplant simmered in a soy-dashi bath until silk-textured and deeply savory — a quiet standout on the menu.
- Otoro aburi — $35: Seared fatty tuna layered with crisp vegetables and a silky kimijoyu (egg-yolk) dressing; fresh wasabi provides lift.
- Yamitsuki cabbage — $16: Crunchy cabbage tossed in sesame oil and garlic for strong umami notes; sweet potato fondant rounds ($16) arrive caramelized with a bright, tart counterpoint.
Not every dish aims to be showy; several vegetable plates feel intentionally scaled to balance the heavier options, giving the menu a more sustainable rhythm for multi-course meals or sharing groups.
What to drink
- Three sommeliers are on staff to recommend sake, wine or cocktails. A standout pairing led staffers to highlight Miyashita Brewery’s “Sunshine Country” junmai, an earthy sake with sesame-like notes that pairs well with both eggplant and beef.
- Each night the team opens a magnum for a special by-the-glass offering; a recent selection was a 2022 premier cru aligoté from Domaine Ponsot.
Insider tips
- A wagyu sandwich on milk bread is listed as an upcoming addition — a casual share item meant to showcase grilled beef in sandwich form. Pairing it with the Caesar salad with grated egg ($22) makes for a fuller meal.
- On your way to the restrooms, take a quick look through the cellar door: the list includes heavyweight bottles such as Petrus, DRC and La Tâche.
Koshu Club’s arrival is notable less for revolution than for repositioning: it brings Michelin-caliber technique out of the counter and into a convivial dining room, where guests can mix high-end wagyu, thoughtful vegetable work and guided sake choices without committing to a full omakase. For diners who want a less ceremonial route to fine ingredients, that shift matters.
