I went there last year to check out the hype.
Got to seat at the bar to watch them prepare all the food. I'll have to say all those guys are are platers. Nothing is freshly made on the spot and it tasted burnt! The waiters were aggressive and constantly reaching over to take stuff away from us. I had ordered their pork bun, and ramen and a beer. The beer came in a tall boy can, no glass and I had to open it myself for $10 (talk about self serve!).
Food - Meh! I have instant noodles that are WAY better tasting, and I mean it. I'll take instant noodles any day over momofuku noodle bar.
