We had been recommended this restaurant by friends and went on a friday night. We arrived between 8:30-9pm and were given a table upstairs straight away. The restaurant was really busy and there was a great atmosphere, everyone was talking in an animated way and there was a lot of laughing going on!! The service and food were great, we jad the mixed sashimi plate and the mixed tempura- the tempura was particularly good, very light and crispy batter! The restaurant is undermeath the yamanote line so theres lots of train noises, but this only added to the atmosphere!
