Wagyu from $235 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
The Charter Oak, Chris Kostow's more casual St. Helena restaurant, currently lists a '32oz American Wagyu Tomahawk' ($235) with brown butter hollandaise as its marquee shareable steak. Wagyu appears as a single feature cut rather than a dedicated program, and no producer, breed status, or grade is disclosed. The separate tartare on the current menu is an 'Aged Beef Chuck Tartare,' not the Wagyu tartare cited in older sources.

Common questions
- Does The Charter Oak serve real Wagyu?
- Its own current menu advertises Wagyu, and that claim was read directly on July 17, 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 The Charter Oak serve?
- Its menu discloses American Wagyu. 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 The Charter Oak 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.
