Wagyu from $16 on the menu we read · up to $35
This listing's current published materials advertise Wagyu, but the offering does not meet our full verification standard for provenance. It carries no authenticity badge; undisclosed details remain explicitly unverified.
Why it's listed
A small, modern Edomae-leaning sushi counter on Sound Beach Avenue in Old Greenwich, run by executive chef Rio Yonathan, serving nigiri, sashimi and maki alongside a $110 chef's-choice omakase platter. Two dishes carry Japanese A5 Wagyu: an a5 wagyu nigiri with soy glaze and garlic chips, and a wagyu and crab roll built with blue crab, a5 wagyu, avocado, cucumber and spicy mayo. The menu states the A5 grade on both but does not name a prefecture, brand or farm. Dinner only, Monday to Saturday.
Authenticity flags
- Both Wagyu dishes are listed as A5 but the menu does not say which prefecture or farm the beef comes from. Ask at the counter if provenance matters to you.

Common questions
- Does Sushi Bar serve real Wagyu?
- Its own current menu advertises Wagyu, and that claim was read directly on July 22, 2026. What the menu does not do is say which Wagyu: no prefecture, grade, breed status or producer is published, so the sourcing cannot be checked from outside. That is a gap in what is written down rather than a suggestion that anything is wrong with the beef, and plenty of kitchens buy carefully without printing the details.
- What kind of Wagyu does Sushi Bar serve?
- Its menu discloses A5 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.
- Why is Sushi Bar listed without a Wagyu badge?
- Because a badge here means the sourcing was checked, not that the food is good. This listing is published because the venue genuinely advertises Wagyu on its own current material, and it carries no badge because that material does not say which Wagyu. If the venue publishes the prefecture, grade, breed status or producer, the listing can move.
