Boyfriend and I stumbled upon this place completely by accident as we were wandering the strip. We needed a place to eat and saw their name as we walked by the Monte Carlo. When we realized they served ramen, we figured -- oh hell, why not?
The restaurant is bigger than it looks from the outside, with seating extending deeper into the building than we thought. I ordered the Logan Poser and Boyfriend got the Many Mushroom. The portions were decent for the price, but keep in mind that you're definitely paying the Vegas upcharge. Not that ramen back home in San Francisco is much cheaper, but be aware that it'll probably be about $15-20 per person.
I thought everything tasted pretty good and the staff were very nice. If you're seated near the inside entrance, you'll be able to people watch everyone walking around the Monte Carlo casino. Essentially, if you're craving ramen and you're unable to leave the strip, then Yusho is probably your best bet.
