Grant Achatz protégé David Posey is the latest in a parade of highly touted guest chefs to fill-in for Rogue 24 chef R.J. Cooper, who is recovering from open-heart surgery. Posey, currently the chef de cuisine at Blackbird in Chicago, will helm the open kitchen in Blagden Alley for five nights, beginning on Feb. 7. Seats are all taken for D.C.’s own José Andrés’ week-long stint in the Coop’s kitchen, starting Tuesday. Tickets for Posey’s visit, available Monday at 10 a.m., are $185 a pop with $10 from each purchase going to charity. Get yours here.
