The northern Thai noodle soup: coconut curry broth, egg noodles, fried noodle topping, chicken or beef. Iconic.
Khao Soi Khun Yai and Khao Soi Mae Sai are local favorites. 60–90 baht per bowl.
Also try sai oua (grilled herbal sausage), nam prik num (green chili dip), and gaeng hung lay (slow-cooked pork curry).
