I have been eating at Japanese restaurants for 30 years and have been to Japan, but I never have seen any soup like this before. Tan Tan Men is a not-too-spicy miso based broth with ground pork, bean sprouts, seaweed and ramen. So delicious. I can't imagine a better dish if you have the sniffles, which I happen to have...If you're in San Mateo, I highly recommend it.
