Wagyu from $55 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
Chef William Eick's intimate Oceanside tasting counter serves a ten-course seasonal menu at $225 per person, built around California seafood and produce read through Japanese technique. A5 Wagyu is offered as a $55 per person supplement, served sukiyaki style with onion. The grade is stated on the venue's own menu, but no prefecture, brand or producer is disclosed first-party.

Common questions
- Does Matsu serve real Wagyu?
- Its own current menu advertises Wagyu, and that claim was read directly on July 20, 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 Matsu 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 Matsu 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.
