I have eaten at Storen Korean Kitchen (ground floor of 4 Embarcadero in SF) several times recently and wanted to bring this great little place to the attention of fellow CHers. The soon du bu (spicy seafood and tofu soup) is to die for! It comes to the table sizzling hot in a stone bowl. The menu describes the tofu as "silken" and that's the perfect description. It is so soft and smooth. It also contains a generous amount of seafood (shrimp, claims, squid). They also bring an egg (in shell) with the soup, which you break into the soup and it's cooked by the heat of the soup. You can get it mild, medium or hot. Medium is perfect for me - hot without being too hot. Warning, if you order the soon du bu hot, it is very hot. Their bi bim bap is also excellent, with a fried egg served on top. Finally, I recommend their stone wings appetizer - fried chicken wings in an excellent sauce. There were some early posts about this restaurant shortly after it opened noting some problems with the service, but those were just break-in issues typical of any new restaurant and have been cleared up. Service is fine now.
