I would give 3.5 stars and my wife would probably give 5, so four is about right.
Nice place located in a basement and isn't unlike some of the places I visited in Japan, size being the biggest departure. No internet service, that can be a good thing.
Menu was large with plenty of options. We had two appetizers; one was a sashimi mackerel that was fried after the meat was gone and the other was a giant Clam in ginger sauce served in the shell. Do not remember the names but both were good. Also had two sushi rolls and both were tasty, if not the best I've had.
Martini was ok and the beer prices at happy hour were great. Even with the affordable drinks, bill was nearly one hundred USD.
One thing was their Wagyu beef on the menu is Australian. Not a big deal but the chef seemed to think all Wagyu is from Oz. umm, no it is not. Most here in the States is, but I will not pay 100 for six ounces if it isn't from Kobe.
