Some 189 restaurants and street-side eateries have been awarded the Bib Gourmand label by the Michelin Guide for being the best value-dining spots.
The label adds to the government's promotion of food tourism.
The selected eateries include 53 new entrants on the Bib Gourmand list and six that were elevated in the rankings.
Some 82 are located in Bangkok and its surrounding provinces, 13 in Ayutthaya, 27 in Chiang Mai, 23 in Phuket, 11 in Phang-nga, nine in Nakhon Ratchasima, six in Ubon Ratchathani, seven in Udon Thani and 11 in Khon Kaen.
Key criteria for the Bib Gourmand label are the quality of ingredients used, distinct taste and creativity in cooking. Dishes that reflect the character of the chef also score higher, while value for money and consistency in taste of the same dishes savoured at different times are also important.
