Wagyu from $33 on the menu we read
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 Peruvian-Japanese restobar in Downtown Crossing serving Wagyu three ways. The Wagyu Mofu at thirty three dollars is torched a5 wagyu with cucumber, avocado, asian pear, huancaina, rocoto chili butter and shiitake bacon; a Korean Steak Tartar uses wagyu beef with yukke sauce and kimchee mustard; and Wagyu Steak Anticuchos are grilled skewers with rocoto chili salsa and yuzu butter. The A5 grade is stated but no prefecture, brand or farm is named beside it.

Common questions
- Does RUKA serve real Wagyu?
- Its own current menu advertises Wagyu, and that claim was read directly on August 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 RUKA 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 RUKA 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.
