Izakaya is a decent chain of traditional Japanese fare and comes very close to a lot of the authentic stuff I had in Japan during my time there. I'll come out and say it, if you have a very narrow view of what Japanese cuisine is, then this is definitely not the place for you. This place has great ambiance and an unusual but effective seating arrangement that maximizes the space. Staff is very friendly and in my experience is very precise in carrying out requests/orders even if service is on the slow side.
What I will say is the current pricing definitely does not add up, portions are very small but this is supposed to be a higher end establishment so I kind of expect it, even though booze is on par with competing bars and resto pubs in the area. Food is subtly seasoned as is tradition within Japan, so if you're looking for something super exotic you will be disappointed. What you can expect is good healthy food that wont leave you feeling guilty after, even if your wallet may feel violated.
