Madcow Burger by Toni Santos Asok is a small burger shop in Asok, Bangkok that serves handmade beef and chicken burgers. The Madcow Burger and the Asok Burger come with thick, juicy patties topped with cheese, sauce, and vegetables on a soft bun. You can eat at small tables beside the road or order through Grab delivery. The shop is open-air, so it is hot while you eat.
