Craft beer izakaya. Either 70 or 100 beers on tap depending on which sign or menu you're reading. They also have a happy hour between 5 and 8 where you get a free small plate of food with every drink. The fried chicken and sausages are both fine as a free beer snack but I wouldn't pay for them.
It's a busy atmosphere and the staff are nice, although they seemed to be confused by my request from sample a couple of beers before making my choice.
