My girlfriend and I will be taking an extended vacation to San Francisco next month. While we're both very excited about the trip (her first time to SF), there's one thing that concerns me. The problem is that "she-who-must-be-obeyed" will REQUIRE Korean food at least once or twice during our stay (we'll be there for three weeks), and I don't recall ever reading about any decent Korean joints in the city. I went back 17 pages and did a search of this forum to no avail. Can any of you kind souls point me in the direction of a good Korean restaurant close to the Russian Hill district? We'd prefer to walk or use mass transit if at all possible, but we will have a car if we have to go further out. Also, we're planning on Gary Danko/Fleur de Lys for a few dinners, but since I also need to make mortgage payments, I need suggestions for good and cheap eats in the area. I understand that Chinatown is in walking distance of where we'll be staying (Lombard and Leavenworth), so I imagine we'll be eating there quite often, but other recs will be greatly appreciated.
