The famous, ever-evolving Ray’s Hell Burger restaurant in Rosslyn, often named on lists of the best burgers in the United States, is closing.

Signs up at Ray’s Hell Burger, at 1650 Wilson Blvd, say it is going on “hiatus.” Last night an employee told ARLnow.com he did not know when it would reopen.

“Beginning Sunday, May 14 this location of Ray’s Hell-Burger will be on hiatus. The last service will be on Saturday, May 13,” the sign says. “Please continue to visit Ray’s Hell Burger at 449 K Street NW, 7 days a week. Ray’s the Steaks accepts reservations 7 days a week at 2300 Wilson Blvd (sorry, no burgers).”

Owner Michael Landrum could not immediately be reached for comment.
