We ended up at Yusho on a Thursday night in late August. My wife and I started with pork shoulder steam buns, followed-up by our Ramen. I opted for the Logan Poser, and my wife had Spicy Shrimp. Both dishes were incredible - great flavour, huge amount of protein and a reasonable size.
Service was decent; good enough I should say.
Atmosphere was pretty rough, and this is the only reason it lost a star in my mind. Feels like you're sitting in a cafeteria, and there were very few other diners in the restaurant at 7:30 p.m. Hopefully this is because it was a Thursday night!
Tip: the MyVegas 2-for-1 Ramen is a great deal!
