First of all, I think Nishikawa Ramen is a 4 star ramen place if you have to compare it with just the ramen in ARIZONA. I honestly think it is a lot better than most of the ramen I've had here, including the ones in top notch Japanese restaurants in the valley. If I were to compare it to the ramen in LA, it wouldn't come close to 4 stars. I still thoroughly enjoyed my meal nonetheless.
For the ramen, I was told the Nishikawa black was the tastiest one but I opted for the tonkotsu. It was good; it was definitely on the salty side. The pork was fatty and tasty, not as tender as I would like it to be but it was not bad. We also had the beef bowl which was excellent. Our server warned us that the meat would be fatty. It was so good and tender. I couldn't believe that it only cost us $5.
I will definitely be back to try the other ramen styles.
