A hostel owner in Chiang Mai showed me how to eat for $3 a day and I still use his trick
He walked me to the back of the Sunday market where the food stalls were half price after 8pm, and pointed out which vendors gave free rice with any curry. That was 6 years ago and I still plan my whole travel day around when the cheap food shows up. Anyone else got a local who taught them something no blog ever mentioned?
