We can go there for lunch or dinner. My personal recommendation is to get the one coin lunch because we can eat various set meals for a mere 500yen. They have eat tempura, sashimi and sushi at dinner time.
One of the things I like about is that we can take off our shoes (like we do in our homes) and relax. On the first floor it is tatami private room and on the second floor it is tatami big room which can seat more than ten people.
