Thong Sala has a food night market which consists of multiple food carts ranging from ready made curry stalls, made-to-order restaurant carts, noodle carts, chicken vendors, and desserts such as Thai confections and banana rotee (pancakes).
Whoever invented night markets is a genius.
You can get a complete meal for a few Bahts and delicious, if you don't mind sitting on a plastic table and chair.
