Ongtong Khaosoi is a restaurant on the main street by Ari Station that serves northern Thai khaosoi. The khaosoi comes with a choice of chicken or meat, along with fried noodles and a curry broth with a strong coconut milk aroma. A photo menu on the second floor makes ordering easy, and visits on weekday lunchtimes have been recorded without waiting. The khaosoi broth is on the salty side.
