After breakfast, I managed a quick nap in my hotel room (thanks Hilton for letting me check in at 8am - must be my record of earliest check in at a hotel), and after that I was all refreshed and ready for lunch at Den, a restaurant owned by the young Chef Zaiyu Hasegawa that many of my friends have gone and loved, and now it became so popular that I needed to call them a month in advance to confirm a spot.
