Follow the hostess through the tall black gates of Villa Casa Casuarina on Ocean Drive, into the courtyard, then upstairs to a pair of heavy wooden doors. Behind them: a dark space with a wooden vaulted ceiling crisscrossed by intricately inlaid beams. This is Italian designer Gianni Versace’s former suite, converted into a Japanese speakeasy that offers intimate, four-seat omakase experiences. As at Sushi by Bou’s locations in New York City, chef David Bouhadana is the itamae behind the creations — all 17 pieces, ranging from smoked lean tuna crowned with a dash of gold flakes to uni (sea urchin) on seaweed or a scallop topped with volcanic salt. Your reservation includes private access to the G-Lounge, Versace’s original cigar room, a cozy space equipped with a personal bartender who serves Japanese whiskies and craft cocktails, not to mention leather couches, a fireplace, and a Mr. Sake machine. Seats are released one month in advance, and reservations must be made through the restaurant’s website or OpenTable and paid at the time of booking. New Normal: For a private dining experience, reserve the entire room and invite family or friends.
