Much has been made of the obscure location, and finding it (down a dark alley) is quite an adventure. Throw in a rather subterranean dining room (no windows) and minimal English language in use and it does feel a bit like a foodie rabbit hole. The teeny menu is all about egg noodles in fantastically complex, homemade clear soup. It comes in a few guises with wonton, beef brisket, pork hock and pork stomach among the options. The duck is the pick; a whole Maryland, marinated in spices then cooked until chopstick tender, floats in a huge bowl surrounded by bok choy and noodles with a side plate of sprouts and chrysanthemum leaves.
