Chef Zaiyu Hasegawa’s modern Japanese cuisine is served in a playful and relaxed atmosphere. A large communal table takes center stage, and conversations with new friends fill the air. Fried chicken stuffed with seasonal ingredients and a colorful salad are two of Den’s signature dishes. The jovial and sociable environment, which reflects the chef’s energy and attitude, is rare for a high-end restaurant. The kitchen overlooks the dining room, and Hasegawa comes out to talk to the diners as if he’s hosting you in his home. Den is a treat for anyone lucky enough to get a reservation.
