Wagyu from $36 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
Soi is a Thai restaurant and bar in Kirkland. Two of its dishes are built on Wagyu steak rather than ground beef: a Waterfall Steak at 36, grilled and tossed with toasted rice powder, red onion and mint, and a barbecue plate at 36 built on an eight ounce Wagyu steak marinated in soy, garlic and lemongrass. The menu says the beef is from the USA and stops there, naming no ranch and no breed generation.

Common questions
- Does Soi serve real Wagyu?
- Its own current menu advertises Wagyu, and that claim was read directly on August 23, 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 Soi serve?
- Its menu discloses American. 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 Soi 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.
