We got ramen, takoyaki, and the seared char-siu. Everything was really delicious, and the service was great! The servings are more generous than most ramen places, so I would wait before ordering noodle refills (I made this mistake). The takoyaki especially was melt-in-your-mouth good, so I would definitely recommend getting that! I agree with the other reviewers in that the ramen here isn't overly salty as is typical of ramen restaurants, which is wonderful.
What's also cool is that you have the option to tailor not just the toppings but also the spiciness level of your ramen to your taste. Would definitely recommend on your trip to Vegas!
