I wonder about the accuracy of this "closed" marking on Yelp. I just visited Ku Noodle a couple weeks ago and I have seen no local news reporting the closure.
Anyway for what it's worth, Ku Noodle was a very original restaurant that broke the mold of what you normally see in big Vegas casinos. I ordered the Ku Monk noodle bowl, the Shumai, and the "bowl of cereal" shaved ice dessert. The shumai was a small, but very tasty dim sum syle dumpling dish. I was very impressed with the freshness of the ingredients in the noodle bowl. And the dessert was like nothing I've ever had. The description of "bowl of cereal" was very accurate. It tasted like a frozen bowl of cap'n crunch.
I hope that the restaurant stays open. If it is really closed, I hope the SLS replaces it with a quality offering and avoids a safe or trendy pick that lacks real substance.
