Visiting LA recently I recalled a trip to Harbor Kitchen and suggested we go for Chinese food. My father suggested Din Tai Fung which is famous for their soup dumplings. We got there at 4:15 on a Saturday and were just ahead of what by the time we left was a fairly major line. Yes, the soup dumplings are all that, and there are good non-pork and even vegetarian options. But don't neglect the rest of their menu. We also had the excellent Shanghai rice cakes, which had a sauce sort of half way between a brown sauce and a curry+Szechuan peppercorn sauce like you'd find on Singapore noodles. They have some tasty greens as well. Highly recommended.
