This research looks at the impact of marketing and branding of street food in Chinatown, a famous street food area within Thailand's capital city Bangkok. The objective of this research is to analyze the impact of branding and marketing street food businesses through social media. To analyze and interpret the impact of branding and marketing through social media, this research asked 208 individuals through questionnaires. Although this research is based on the street food available in Bangkok's Chinatown, this research is of benefit to anyone who currently engages or intends to engage in the street food business. This is particularly accurate, if the street food businesses are within Southeast Asia and/or areas with similar weather conditions.
