JINYA is perfectly alright, but not better than a lot of other places in town. For me, I think it will be a "change of pace" kinda place. Their flavors are a bit unusual and they offer a wide selection of optional toppings. The location is more convenient to me than most other ramen joints. The customer service was fine.
They are a little expensive considering the bowl leans small (they look big, but the ceramic material is just really thick and tall), and the toppings are a little stingy in portion (probably because the bowl is small). Ramen prices in Vegas seem to be creeping up in general. It was also odd that the "thick" noodle ramen (what I would call normal) in my husband's bowl was super small portion, while my thin noodles (the thinnest I've ever seen in ramen) were pretty generous. I ordered tofu as a topping and it was cold, not cooked, and cooled down the ramen faster. But it was an entire brick worth of tofu. The fried onions are quite tasty and I enjoyed the chicken char-siu, still kinda rare.
The spicy is really not spicy (like maybe 1.5 on a scale of 5) - it did make the ramen more flavorful but also more salty, I think. JINYA ramen was definitely saltier than average. I think I'll try the basic chicken ramen next time and see if it's less salty. This was enough to make me feel a bit sick soon after.
