Black Restaurant Group’s signature oysters—Old Black Salts and Black Pearls—will make their debut next month.

Restaurateurs Jeff and and Barbara Black are partnering with Rappahannock River Oyster Company of Chincoteauge, Va,. and Toby Island Oysters of Topping, Va., to specially cultivate the oysters.

Diners can get the first slurp at a one-year anniversary party for Pearl Dive Oyster Palace and Black Jack on Sept. 20. The event, from 7 p.m. to 12:30 a.m., will include open bar, food, live music, and plenty of oysters. Tickets are now $150 per person with proceeds going to Food & Friends on behalf of the Black’s Family Foundation. (The price will increase to $175 after Sept. 1.)

Black isn’t the only chef in the D.C. area with signature oysters: Hank’s Oyster Bar has its own called Hayden’s Reef Oysters, named after chef and owner Jamie Leeds‘ son.
