Koshu Club, a new Japanese supper club from Castellucci Hospitality Group and Mujo executive chef J. Trent Harris, is set to land in Buckhead next week. The 45-seat hideaway leans into Showa-era yoshoku comfort, slow-grilled robatayaki and a sake-forward bar that aims to feel like a special-occasion spot you can still treat like your neighborhood haunt.
According to The Atlanta Journal-Constitution, Koshu Club will open April 14 inside the 99 West Paces apartment building, with room for 45 diners total, including 15 seats at the bar. The restaurant plans to serve nightly from 5:30 to 10:30 p.m., and Castellucci told the paper that the average tab should fall somewhere between roughly $100 and $200 per person. The space was built out from scratch and designed by Smith Hanes Studio to feel intimate, moody and deliberately low-lit.
What to expect from the menu
The menu blends washoku, or traditional Japanese cooking, with yoshoku, the Western-influenced Japanese comfort canon, in an a la carte setup that leans into shareable plates and grilled dishes instead of omakase. As reported by Eater Atlanta, the kitchen will fire up binchōtan charcoal for sumibiyaki-style grilling, sending out smoky seafood and premium cuts that highlight texture, char and just the right amount of kiss-from-the-grill drama. Expect a looser pace than Mujo’s counter experience, with more cooked preparations and composed side dishes.
Chef and pedigree
J. Trent Harris, who leads MUJŌ and was recently named a James Beard Award finalist, will oversee Koshu Club’s culinary program. MUJŌ lists itself as a one‑MICHELIN‑starred restaurant on its site, a credential that gives the Buckhead project added weight before a single plate hits the table. For Harris, the new spot is a chance to stretch into a broader range of Japanese dishes beyond the tight omakase format.
The room, drinks and the vibe
Castellucci and Harris say they are aiming for polished-but-relaxed service, the kind of room where you can walk in wearing jeans and a T-shirt and still get the kind of attentive hospitality you would expect from a special-occasion reservation. The beverage program is being built by Mujo’s Michael Satusky, with sake selections curated by Kiki Austin and a large wine list overseen by the restaurant group’s beverage director, according to the paper. In previews, the team has rolled out yoshoku-forward plates and robatayaki-friendly bites, with nods to korokke and rice gratin-style dishes, per The Atlanta Journal-Constitution.
Practical details
Koshu Club’s address is listed as 99 West Paces Ferry Road NW in Buckhead, directly across from the St. Regis, and the team says the restaurant will open for dinner daily beginning mid‑April. Local dining roundups that track seasonal debuts have already pegged Koshu Club as one of the city’s most anticipated spring arrivals. For that broader context, see The Infatuation.
