Perhaps even more than they adore soba and udon, the Japanese love ramen noodles. So do impecunious college students, and it will be interesting to see how many undergrads can squeeze into this fourteen-stool noodle bar specializing in ramen and delectable pork-stuffed gyoza (the Japanese answer to the potsticker). Loud slurping isn't only tolerated—it's encouraged. — Rob Patronite and Robin Raisfeld
Having been to Momofuku several times I very much believe that Rai Rai Ken offers a superior bowl of ramen. I prefer their noodles and broth much more to Momofuku albeit the remaining ingredients tend to be a little less exotic (the pork belly at Momofuku isn't too shabby). If you want no nonsense Ramen, this is the spot.
Great traditional ramen shop; ignore NYiris' review
This is a retort to NYiris' review: Criticizing a Japanese ramen stand for having "only 3 soups to choose from" is like criticizing a Falafel stand for not selling hamburgers. Traditional Japanese ramen stands usually have exactly 3 ramens to choose from: shio ramen (salt), shoyu ramen (soy sauce), and miso ramen. Rai Rai Ken serves exactly these types of ramen, along with the usual side dishes found in traditional ramen stands in Japan. Uninformed reviews like this cause people (like me) to give them a "10" rating just to balance out the ridiculous grade that this reviewer gave. Look at reviews for Rai Rai Ken at any other site, and you'll see people reviewing it as one of the top 3 ramen shops in the city (an evaluation I would mostly agree with). I've haven't found any ramen shops in NYC that would rival the ones in Japan, but as far as state-side ramen goes, Rai Rai Ken is great (and it's fantastically cheap!). If I were to give it an actual rating, I'd give it an 8, but I had to bump that to 10 to balance the scales.
