I have been going to Hachi for years and LOVE it.
I usually always get the Omakase. For a long time it was pretty much the same with only couple new plates updated over the years. But, it never bothered me because it was always top notch!
Last weekend I was pleasantly surprised to taste an entirely new chefs selection! Everything about the night & menu was exceptional including the server, and the bottle of saki he recommended.
Hachi is great cause it's never overly crowded, nor does it seem super pretentious, for more of a fine dinning sushi place. The giant wall of eyeball art always intrigues me.
They also have some of the best oyster shooters I have had in Vegas.
I have had a few things from the regular menu as well, and they never disappoint.
In my opinion, much between than Nobu.
