We are two Americans visiting Japan for two weeks and this was by far our best meal of the trip, including another Kobe Tappenyaki place.
The staff was extremely nice, the beef was obviously delicious, the price was great, and the vegetables were fantastic. They served the beef slowly as we ate it so that we always had freshly cooked and hot beef (rather than dumping it all on our plates at once, as the other place did). They would suggest what sauces, vegetables, and meats to pair together. The music was a great volume, and overall it was just a really wonderful meal. I wish we had gone back here instead of trying another place, but unfortunately we were in a different city by then.
Definitely make this a stop on your trip!
