Highly recommended.
The restaurant can only seat about 15 customers at one time and because of that, we get to enjoy the excellently cooked A5 Wagyu beef while having a nice personal chat with our young, cheerful and skillful chef Wabi-san. For instant, I casually asked about the grading of the beef and they went all the way out to retrieve the certificate and some other info to explain to me.
Truly enjoyed the meal and will definitely return if I back there.
