Popular downtown Rx Restaurant on Castle Street has purchased The Kitchen in The Forum shopping center.

The Kitchen’s previous owner, Ash Aziz, on Monday confirmed that the sale had closed. Rx owner/chef James Doss said today (Tuesday) that he will bring an Rx-like concept to the nearly 7,000-square-foot 1125 Military Cutoff Road unit at The Forum’s south end.

The new location, however, will have its own name and identity.

“It will be the same sort of [Rx] idea but we’ll definitely do some different things,” Doss said. “You’ll have to go to Rx to get certain things, and you’ll have to come to the new place to get certain things.”

The thread holding the two places together will be the Rx motto: “seasonally inspired, ingredient-driven, Southern cuisine,” Doss said.

Opening day is scheduled for October.

The restaurant will serve dinner six days a week and will close on Monday. Lunch and/or brunch may begin in 2014, Doss said.

The Kitchen’s interior design scheme won’t change much, Doss noted. A back area will be curtained off as a private dining space, the bar will be altered, and an effort will be made to lighten the dark dining room, which seats around 200 people. Doss said he plans to keep the open kitchen, which diners see behind a glass partition.

“I think it will be good for [Doss] and good for the community,” Aziz said of the expansion.

Doss agreed, noting that with Rx on track and heavily tapping the downtown market, the time seemed right to move into the Mayfaire/Landfall Wilmington market. Plus, The Kitchen was nearly ready for move-in, with only minor changes and cleaning required.

Prior to opening Rx, Doss, years ago, worked for Aziz at Aziz’s former Max’s Prime Steakhouse -- now home to a different owner’s 1900 Restaurant and Lounge at Lumina Station. Doss said that as he considered opening a store in Wilmington, he tapped Aziz for advice.

Doss’ last gig before he and business partner Josh Novicki, friends since childhood, developed Rx was at well-respected Husk in Charleston, S.C. Novicki has worked area restaurants, too, and spends part of his time as a professional disc jockey.

Rx has won positive reviews and its fan base has steadily grown since the restaurant’s July 2012 debut at Castle Street and Fifth Avenue.

The menu is focused on local foods and changes nearly daily. Popular signature dishes are Buffalo-sauced, crispy fried pig ears to dip in blue cheese dressing; shrimp and grits with andouille sausage and seasonal vegetables; and roasty pork belly resting on creamy cheddar grits under a poached egg.

Aziz locked The Kitchen doors in June after about an 18-month run. The Kitchen opened at 2011’s end, replacing Aziz’s former Grand Union Pub there.

Aziz’s Circa Restaurant Group also includes downtown’s Circa 1922, Towne at Mayfaire Town Center, Boca Bay and Brasserie du Soleil, both on Eastwood Road near Wrightsville Beach, and Osteria Cicchetti at The Forum.

Aziz is working on a second Osteria Cicchetti location, which he said is scheduled to open in October at Monkey Junction.
