I have hated on Momofuko in the past, but no more. After visiting Rai Rai Ken, I have come to the realization that Momofuko Ramen is pretty good. Additionally, you can have the steamed pork or crispy chicken buns. All in all, I would rather go to Momofuko (but early to avoid annoying crowds or people that think they are really cool bc they read TONY and they now the cool spot to go). Sorry had to release a little rage.
Anyway, the broth at Momofuko is a bit thicker and better tasting. Also, the bamboo shoots, which I love, are tastier at Momo. Lastly, and I never thought I would say this, Momofuko has more space than Rai Rai.
I have yet to try Minca, but I guess I should, right?
