The Copper Onion
Salt Lake City, UT · New American
Tier 3 · Menu claim only What the tiers mean
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 longstanding downtown Salt Lake City brasserie with a genuine multi-item American Wagyu program. The current dinner menu lists a Wagyu Beef Stroganoff over pappardelle made with Snake River Farms beef, a Wagyu Steak Frites cut from a Snake River Farms zabuton, and a Wagyu Bone Marrow starter. The beef is credited to Snake River Farms, a well-known American Wagyu producer, though the menu does not state the breed generation (fullblood, purebred, or F1). Open daily for lunch, dinner, and weekend brunch.

Common questions
- Does The Copper Onion serve real Wagyu?
- Its own current menu advertises Wagyu, and that claim was read directly on July 27, 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 Copper Onion serve?
- Its menu discloses Snake River Farms. 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 Copper Onion 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.
