The name of the restaurant [six un six] means "616" in French. The restaurant opened on June 16, the same day as the anniversary of the couple's vow to open a restaurant together. The restaurant offers French-based cuisine by Chef Yutaka and sweets by Pastry Chef Mao. Five to six kinds of fresh cakes are available for takeout, and about 15 kinds of baked sweets such as canelés and financiers, which are baked until just before they burn, are also excellent.
