Came here on a Saturday morning right as they opened. I was greeted by a friendly cashier who took my order and yelled behind her what to prepare. Its a VERY small establishment, with only a couple of bar tables in a small side area if you want to eat there.
4 stars is for the fact that my spicy ramen was delicious, and what you would expect from a vendor in a shopping mall for a decent price. Keep in mind, I don't eat a whole lot of ramen and am probably easily pleased so if you are a ramen connoisseur take my review with a grain of salt. I thought the noodles were perfectly cooked and I watched them add the fresh ingredients at the end (little soggy by the time i got up to my room, but still delicious). Yes its served in a plastic container so you can take it with you, but they did offer me a bowl if I wanted to dine-in.
Overall I was pleased and will return during my next adventure in Vegas.
