Sullivan’s Steakhouse, on the first floor of the U.S. Steel Tower in Downtown Pittsburgh, closed this week — less than four years after it opened.

No reason was given for the closure.

“Due to unforeseen circumstances, we’ve made the difficult decision to permanently close our beloved Pittsburgh restaurant,” the restaurant said in a statement to TribLive. “We are incredibly appreciative of the support this community has shown us over the years and encourage our loyal guests to continue to visit our sister concept, Eddie Merlot’s.”

Sullivan’s opened in October 2021.

Sullivan’s, with 14 locations across the United States, is owned by Dividend Restaurant Group. The Denver-based company also operates Eddie Merlot’s, a steakhouse with a Downtown Pittsburgh location.

The restaurant’s name was inspired by John L. Sullivan, a bare-knuckle boxer in the late 1800s. There were photos of him throughout the Downtown restaurant, including a fight in Pittsburgh.

The 7,600 square-foot restaurant had a seating capacity of 250 along with private dining rooms and temperature-controlled wine lockers.
