Rat Na Yot Phak 40 Years is an old shop in Bangkok's old town near Khao San that serves rat na, a Thai-style thick noodle dish. The noodles are wide sen yai rice noodles with a charred wok flavor, topped with pork and vegetables in a thick starch gravy. Items 1 and 13 can be ordered with added rice, and item 13 comes as a seafood stir-fry. It is a taste you try once and do not want to eat again.
