I wouldn't say much about the ambiance there - it's crowded and minimalistic. But that's not why you go there. The food was great - we started with the famous pork buns, which were delicious - although, not what we were expecting:
The buns are soft, almost pita-like, and filled with two big pieces of pork with a hoison sauce. They were succulent and very satisfying. For the main dishes, we ordered both the pork ramen noodles and the scallion noodles, both of which were very enjoyable. The scallion noodles were flavorful for not having a broth - the noodles were accompanied by mushrooms and scallions and the ginger just infused the dish with goodness. The pork ramen noodles come with a super-flavorful broth, a healthy portion of noodles, pork (belly & shoulder), egg (that you break & stir into the broth), and veggies (mushrooms, scallions, etc).
After eating our faces off at the Noodle Bar, we decide to have dessert around the corner at Momofuku Milk Bar, which is a place that may be mistaken for heaven. It's crowded and there's not much place to stand, but their dessert options are mind-blowing. We got a swirl of the red velvet cake and the cream cheese icing soft-serve ice creams. It was divine. Getting ahead of ourselves, we also ordered a piece of the chocolate malt cake, which was also superb! If you're a chocaholic, come here & try this ASAP - you'll be in heaven! They had crazy options like cinnamon bun pie, pie with pretzels and potato chips, banana bread ice cream, and so much more. We highly recommend the Momofuku Noodle and Milk Bars and look forward to trying the other Momofukus soon! They are not to be missed...and worth the wait!
