I've been going to MOMO for many years. It is the closest thing I have to a "home" sushi place. I'm eternally impressed with the quality of the fish and the friendliness of the staff. We've gotten to know Jhonny (yes, it's spelled that way) the owner and even see him around Henderson, giving it an even more local feel. The sushi chefs are fairly consistent and are quick to suggest things not on the menu. We are sushi purists (always prefer sashimi to anything resembling catfood and/or covered in "yumyum" sauce!) and usually go in and request "the best fish you have." This can be dangerous for the wallet at times -- but always results in luscious, large chunks of fish.
I've grown especially fond of the AJI (spanish mackerel sashimi). The body of the fish (skeleton, tail & head) are used as a serving plate for the sashimi. After you are finished, the take the fish body, fry it up, and reserve it to you as a crispy snack.
