From the Hotel Costes team, At Sloane brings Parisian moodiness to a discreet Chelsea townhouse. Slip through the unassuming entrance and head upstairs to the beautiful top-floor dining room, where skylights, hints of red and intimate interiors feel stylish by day and sultry after dark. The menu offers Hotel Costes favorites — including nems and cheesecake — making it just as good for a chic lunch, drink or moody dinner.
