Why it's listed
Chef Brian Lewis's Japanese room in the restored Vigilant Hose Company firehouse on Wilton Road in Westport, serving a seasonal nigiri and hand-roll menu plus a 15-course OKO-KASE counter tasting at $200 per guest. A5 Miyazaki Beef appears three ways on OKO's own Westport documents: as nigiri with truffle aioli and crispy leeks, as a Boujee Temaki hand roll, and as the beef course closing the OKO-KASE nigiri progression. A separate Spicy Wagyu Beef crispy with truffle and quail egg is also offered. The Westport menu prints no prices; OKO-KASE requires 48 hours' notice.
Authenticity flags
- The Spicy Wagyu Beef crispy does not say where its beef comes from, unlike the A5 Miyazaki dishes elsewhere on the same menu. If you want the Miyazaki beef specifically, order it by name.

Common questions
- Does OKO Kitchen serve real Wagyu?
- Yes, and it says where the beef comes from. OKO Kitchen in Westport, CT publishes enough detail on its own materials to identify the Wagyu it sells, which is the standard this directory calls verified, last checked on July 22, 2026. That means a named Japanese brand or prefecture with its grade, an American breed status with a named producer, or an Australian producer with a marbling score.
- What kind of Wagyu does OKO Kitchen serve?
- Its menu discloses Miyazaki A5 and Japanese. Each of those is taken from the venue's own current materials rather than from a review or a listing site, and the evidence behind it is quoted further down this page.
- How was OKO Kitchen verified?
- By reading the venue's own current material, its menu, its site or its ordering system, and quoting the line that names the beef. Reviews, aggregator copies and press mentions are not accepted as the source, because they go stale silently. Verification is assisted by AI and every claim is stored with the page it came from, last confirmed on July 22, 2026.
