This is beyond a shadow of a doubt, my favorite ramen place in Las Vegas.
Ramen is an easy 5/5. As a matter of fact, sans the Chashu Don and Ice Cream sandwich, the place only serves chicken-based broth ramen. Their whole menu is in a little sheet of paper you fill out when giving your order. You can do add-ons to your ramen, but that's pretty much it.
I always order the Tori Paitan Ramen + Black Garlic Oil with a side of Asahi. Excellent tasting broth, chashu is torched to add texture and crunch, the bamboo shoots taste great and do not smell, and the green onions add a lovely tang.
The place only does a ramen bar but it's wide. Super clean, super comfortable. The waitress regularly checks on you and the chefs make sure you're doing ok. Other than that, everything else is self service, which I believe translates into a no pressure / no rush environment.
5/5 in everything. My ramen go to place.
