Turns out the list was ranked based on votes from travellers who are also food lovers. According to the US’s business magazine, 92,000 business travellers and 1,400 corporate travel agents from over 86 countries and territories took part in the survey.
The survey measures the cities on four parameters: number of street food vendors, affordability, number of street food experiences, and food hygiene.
In the list, Singapore was ranked first, followed by Bangkok of Thailand and Hong Kong (China). Ho Chi Minh City of Vietnam was in the fourth while Mumbai of India was in the fifth place.
