Aug. 22 will be the last night of service at Broad and Spruce Streets for Ruth's Chris steakhouse, as it's leaving its home of 27 years in the Atlantic Building for more spacious quarters at the Sonesta Hotel at 18th and Market Streets.

The deal - which will thrust one of the city's longest-running steakhouses from the Atlantic Building on the Avenue of the Arts into the belly of the city's corporate scene - caps months of negotiations.

Ruth's Chris will take the former Elephant & Castle space on the 18th Street side, with about 230 seats and three private-dining rooms.

Thursday was emotional for Marsha Brown, who calls the Philadelphia location "my first-born." She later opened branches in King of Prussia and on Long Island, as well as Marsha Brown's restaurant in New Hope. She told staff - many of whom have been with her for two decades - about the date of the changeover.

The look of the new location will be "swanky," said Brown. "That's the word I keep coming back to." The current dining room's atmosphere has been described, somewhat cheekily, as "Teddy Roosevelt's trophy room." Center City's BLT Architects and New York's Beth Donner Design have the commission.

"You'll still be able to hear the sizzle [of the butter-topped steaks] from across the room," Brown said.
She hopes to open between mid-March and early April 2016.
The Sonesta finished a $30 million revamping of the hotel (previously known as the Crowne Plaza Philadelphia) last fall. The new Ruth's Chris will be next to the hotel’s existing bar and lounge - Art Bar - and its in-house art gallery, which features works in partnership with the Center for Emerging Visual Artists.
