Yaowarat Road is well known for one of the best street foods in Thailand. There are varieties of food such as noodles, seafood, desserts, and drinks. Prices are reasonable. Business hours are from around 5:00 pm to midnight. One lane of the road is closed especially for pedestrians. I often go there on weekends. Unbelievably there are many street food vendors who received Michelin Guide awards. It's so fun and so fulfill.
