"This dish is found mostly in Chinatown in Bangkok, but it deserves to be eaten everywhere," says Long Chim and Nahm chef David Thompson. "The noodles are dry and that's why they really do benefit from a good marinade. Toss and turn the noodles often to ensure an even distribution of the sauce. I love it when the noodles are overcooked and almost burnt on the edges. Take them that far when you cook them and you'll see what I mean." This recipe can be started a day ahead to marinate the noodles.
