Located in the renovated mansion of Count Nagayoshi Ogasawara, built in 1927, the Michelin-starred Ogasawara Hakusyaku-tei restaurant brings back its extra-fancy Christmas party, decorating the Spanish-style garden with dark red lights and roses, inviting a jazz band and even opening a pop-up casino just for the night. Wear your best and head over for certifiably refined mingling, plus free-flowing Spanish wine and ample barbecued meat, paella and other Iberian delicacies.
Tickets can be booked here. The dress code is black tie.
