Indoor market (selling everything) during the day and outdoor food stalls at night.
"You could pick other food markets (Sompet, Thanin, Chiang Mai Gate, Chang Phuak Gate) and be as deliriously sated, but the night-time street food at Warorot remains special to me. This is the place I discovered sai ua (Chiang Mai sausage), nam prik ong (chilli tomato pork dip) and kaeng khanun (jackfruit curry). The 30 or so stalls are a lively introduction to Lanna and wider Thai cuisine, and because locals come to pick up food for home, the standards are consistently high. Just don’t expect to sit down: eat on the move or take away."
