I ate here for dinner with my girlfriend. First of all, I'm not a ramen critic and I don't know what technically good ramen is. I just go by taste.
All I can say is: it wasn't bad. It wasn't the best ramen I've had, but I enjoyed what I was eating.
Taste: the broth was okay. Wasn't anything special. I had the tonkotsu ramen (salt). It was okay, didn't have a whole of flavor. My girlfriend has the tonkotsu ramen (spicy), she thought it was pretty spicy. I had a taste and I didn't think it was that spicy or had that much flavor.
Service: the staff were very friendly. Nothing to complain about.
Overall: I would say if you are in the area and want some ramen without having to drive far, then come here. If you want the best (in my opinion) go to Monta in Chinatown or Henderson.
