I love YuYu, we have been eating here for a few years now and in the past half year, we must haven been here at least once a week on average.
My favorite is the rice dish, any of them.
After trying many Japanese restaurants in Vegas, I find Yuyu has the best price and quality combination.
It also has the best rice anywhere, as good as the rice I had in Japan.
It's hard the find food as good as in Japan here in the States, so I don't take Yuyu for granted.
My favorite dishes for your consideration as I have tried many things on the menu, compared and contrasted with that from other places:
Sashimi rice bowl
Pork cutlet curry bowl (better curry than places specialize in curry)
Katsudon
Chicken teriyaki bowl
Onigiri
Agedashi Tofu
Egg omelet
