We're coming to SF for a short holiday at the end of March and would like to know what chowhounds on this board think of Le Colonial. The wife thinks it's in Nob Hill or nearby. The other important question is: does anyone know if House of Nan King is still around? (Oh god, I hope so..............) I haven't been to the city for 10 years and yet am still haunted by the scallion pancakes served there. NO idea which street it's on, either, all I remember is getting there early to beat the lines down the street. As I recall it wasn't in Chinatown, though it may have been nearby. Forgive my ignorance and answer my prayers...tell me it isn't gone. (My wife is sick of hearing about it!) Thanks!!!
