Big changes are coming to high-profile Germantown eatery Mop/Broom Mess Hall.

The restaurant opened by James Beard Award-winning chef Tandy Wilson in September is changing ownership and will become a new concept with the same staff, according to a media release.

The new chef at the helm: RJ Cooper.

Cooper, also a James Beard Award-winner, entered Nashville's dining scene in 2017 when he opened modern American brasserie Henley at the Kimpton Aertson hotel. Cooper parted ways with Henley not long after it opened to pursue other projects.

A Detroit native, Cooper has worked under renowned chefs at various restaurants and made his own stamp in the food scene as chef de cuisine at Vidalia in Washington, D.C. He was named Best Chef Mid-Atlantic by the James Beard Foundation in 2007, and he later launched his own restaurant, Rogue 24, offering nightly 24-course tasting menus.

Few details were available Thursday about Cooper's plans for Mop/Broom Mess Hall. He will join the restaurant for a 10-day residency before taking it over entirely on March 1.

The news comes fives months after Wilson opened the Germantown eatery, which was his first new venture since he opened the acclaimed City House in 2007. The Nashville native is widely considered one of the city's best chefs.

Mop/Broom Mess Hall filled the space vacated by Kuchnia + Keller (the restaurant launched by longtime City House sous chef Aaron Clemins, which closed after just eight months) in the old Southern Broom & Mop Co. building at 1300 Third Ave. N.

Mop/Broom served homestyle dishes like the barbecue chicken Wilson grew up eating, but with culinary influences from all over the world.
