Las Vegas has no shortage of ramen places. So, there is much to compare this to. I did not find the broth of the tonkotsu to be as rich or sophisticated as either Go!ku or Monta. It was by comparison much less interesting. Not entirely unenjoyable, but not incredible. So, for me Go!ku is a 5, Monta is a 4, and this is not quite as good, so it is a 3. Service is friendly though and not rushy like Monta, so bear that in mind.
