Very cool little bar, it has that old feel to it, like an old school speak easy. The entrance is just a red door, so you have to know where your going and the interior is a mix or run down cement wall with cement re-bar sticking out of the wall as a coat rack mixed with elegant decor, lighting and a very interesting seating arrangement.
You want to come here for the atmosphere and the experience, I had a few Sake's to tie in the whole experience, and will definitely make this a stop in future outings.
PS don't confuse this place with "Big in Japan" which is a restaurant.. totally different place, but same owner from what I understand.
