Haven't been to Yu-Yu's famous sibling, Ichiza, but Yu-Yu is a pretty strong offshoot of the original. The food we had here was very reminiscent of what we had in Japan.
I tried the grated yam udon noodle soup, which came with two Osaka-style boxed salmon sushi, and I added sea urchin sashimi to my order. We also sampled assorted fried foods on sticks, including eggplant and octopus.
I've had grated yam with udon before, sans broth and served cold. I actually prefer the hot version that I had at Yu-Yu, which came in a bonito-based broth. It was so nourishing and savory. And the lunch special price of $7.95 can't be beat.
Yu-Yu specializes in kushiage; skewered and fried or grilled meats, seafood, and vegetables; so it was imperative that we tried a few of these items. Yu-Yu provides a dark dipping sauce along with in-house seasoned salts for dipping the skewered foods in. Very tasty and somewhat addictive.
Yet another gem located on the magical Spring Mountain Road. Not to be missed on your next trip to Vegas.
