Tha Phae Walking Street

Sunday is the whole point here. From 5pm until 10:30pm, Rachadamnoen Road closes to traffic and fills with stalls running the length of the old city, selling handmade crafts, clothing, silverwork, cheap souvenirs that are actually worth carrying home, and pop-up massage chairs if your feet have given up. Live music happens along the way, and it's free. So are the light displays.

My advice is to go early, around opening, and walk the length before the crush sets in. By eight it's shoulder to shoulder and you'll be shuffling rather than browsing. The temple courtyards off the road are where most of the food is concentrated, and they're calmer than the street itself, so duck into one when you want to sit and eat rather than graze on the move. If you've already done the Saturday market on Wua Lai, you'll spot some of the same vendors and performers. It doesn't make it less worth doing, but manage your expectations on finding anything wildly different.
