Wagyu from $79 on the menu we read
Why it's listed
The Wilmington branch of Sullivan's Steakhouse sits on Concord Pike and serves lunch daily from 11 am and dinner from 4 pm. It publishes its own dinner menu, separate from the one the chain's other branches share, and that menu lists an A5 Wagyu Strip described as Miyazakigyu Japanese Wagyu, seared tableside and served with yakiniku sauce, black lava salt and A5 Wagyu butter. It is sold at $30 per ounce with a four ounce minimum. A Wagyu Bone-In Strip from Snake River Farms in Idaho runs $79, and A5 Wagyu butter is a $9 steak topping.
Authenticity flags
- The menu names the Miyazakigyu brand and the A5 grade but not the individual farm or a certificate number, so there is no origin paperwork to check at the table. Ask the server if that documentation matters to you.
- Three items on the premises carry an A5 label and only one of them is beef. The A5 Wagyu Butter steak topping and the A5 Wagyu Old Fashioned on the bar list are made with rendered Wagyu fat, not a cut of Wagyu.
- This A5 strip is on the Wilmington menu only. The other Sullivan's Steakhouse locations run a shared dinner menu whose sole Wagyu item is an American bone-in strip, so do not expect the same dish at another branch.
- The A5 strip is priced by the ounce with a four ounce minimum, so the smallest portion you can order costs about 120 dollars before sides. The per ounce figure printed on the menu reads a good deal cheaper than that.

Common questions
- Does Sullivan's Steakhouse (Wilmington) serve real Wagyu?
- Yes, and it says where the beef comes from. Sullivan's Steakhouse (Wilmington) in Wilmington, DE publishes enough detail on its own materials to identify the Wagyu it sells, which is the standard this directory calls verified, last checked on August 18, 2026. That means a named Japanese brand or prefecture with its grade, an American breed status with a named producer, or an Australian producer with a marbling score.
- What kind of Wagyu does Sullivan's Steakhouse (Wilmington) serve?
- Its menu discloses Miyazakigyu (Miyazaki prefecture brand) A5 and 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.
- How was Sullivan's Steakhouse (Wilmington) verified?
- By reading the venue's own current material, its menu, its site or its ordering system, and quoting the line that names the beef.
