An intimate, 40-seat restaurant from the Michelin-starred Mujo team, inspired by Japan’s mid-century supper clubs.
A new concept from Castellucci Hospitality Group and Chef J. Trent Harris.
Opening early 2026 at 99 West Paces Ferry Rd NW.
Koshu Club represents the next evolution for Chef J. Trent Harris and Castellucci Hospitality Group, building upon the foundation of excellence established at the one-Michelin-star Mujo in Atlanta.
Inspired by the nostalgic warmth of Shōwa-era Japan and the convivial atmosphere of Western-style supper clubs, Koshu Club merges yoshoku comfort dishes—like omurice, karaage, and tonkatsu—with traditional washoku principles and a dedicated focus on charcoal-grilled sumibiyaki proteins.
Distinct from the omakase format, this 40-seat venue offers an a la carte menu designed for regulars, industry friends, and Buckhead locals seeking a sophisticated yet relaxed sanctuary.
Designed with mid-century Japanese inspiration, the room features dim lighting, rich dark woods, an intimate bar, and seating arrangements curated for both romantic date nights and late-night gatherings.
The “club” in Koshu Club is a nod to the Western-style supper clubs of a bygone era—places where guests linger over drinks, engage in deep conversation, and lose track of time.
Koshu Club is opening in early 2026 in Buckhead at 99 W Paces Ferry Rd NW.
Reservations will be required for most seatings, with limited bar seats available for walk-ins.
Leading the kitchen at Koshu Club, Chef Harris brings his experience from the one-Michelin-star Mujo in Atlanta. His background includes extensive time cooking Japanese cuisine in New York at acclaimed venues such as Suzume, Shuko, and Sushi Ginza Onodera, as well as a tenure at a Michelin-starred Portuguese restaurant, before partnering with Castellucci Hospitality Group.
Castellucci Hospitality Group is an Atlanta-based restaurant group renowned for its thoughtful, chef-driven concepts. With a passion for hospitality and culinary excellence, CHG brings Koshu Club to Buckhead as a sophisticated sibling to Mujo, further elevating the city's dining landscape.
