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.
What does this mean? →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.
