Everyone talks about how hard the Den is to find. The only reason we found it at all is because we knew it was above Chiodo - the amazing mensware store selling Dior Homme and Comme des Garçons.
The promise of good times is in its extensive beer list and impressive range of sakes direct from Japan. Service is friendly, food comes quickly from the large open kitchen and, during the day, a set lunch menu ($18) is projected on the wall. Very cool. Bookings for groups between 5 & 20 only.
