Huai Thap Than grilled chicken or Mai Madan grilled chicken is a chicken dish from the Huai Thap Than district. It is unique and delicacy local food and is famous all over. Its history began around 1937, when Huai Thap Than was a big station for locomotives. They had here to stop to get more woods for steam engine. This is because the train had to stop for a long time, the staffs would go to the forest and get red junglefowl. When they needed to grill the chicken they had to tie the chicken with some pieces of wood. Madan (Garcinia schomburgkiana) woods could be easily found but it turned out that it gave better scent and taste to their grilled chicken. It was first sold at Huai Thap Than railway station until it became unique and famous until now. Chicken grilled with madan sticks has a fragrant aroma and a slightly sour taste. The meat is dry, unlike the famous grilled chicken of other regions.
