Has anyone tried, or is anyone a member of Wagyu Mafia? I had heard of the sandwiches, but apparently, they have a kaiseki and yakiniku restaurant experience too.

My wife and I will be in Tokyo in August and we are looking to have great wagyu coupled with a fantastic dining experience. I had my eye on the stand-up yakiniku restaurant, but there are very little reviews of the experience, so was hoping someone from FT had been. Also, open to other suggestions as well!
