This place is always very busy, but it has devoted clients b/c the food is amazing. I've been a few times, and there has been no "drop-off" in experience. If you can come with a large group 6-8 just around opening time they can seat you quickly. One more hint: If you crave just the pork buns and a beer, get them at the bar and you won't have to wait. Otherwise, the wait is typically 1-2 hours. It's crazy, but people wait. if you appreciate ramen, you should wait too. Every broth is really good. I liked the miso-based ones the best. It's just as good the second or third time as the first. I think that's a sign of a quality place with good management. I expect Ippudo will be around for a while.
