The Old Siam Plaza

The Old Siam Plaza is where Rattanakosin meets old-school retail—an air‑con arcade near Charoen Krung and Tri Phet that locals hit for Thai sweets and fabric runs. From Khao San, it’s a short taxi past Sanam Luang to Wang Burapha/Phahurat. Snack your way through khanom buang hot off the griddle, Foi Thong, Luk Chup, and herbal drinks; most bites run 20–60 THB. Inside you’ll find silk and lace stalls, gold shops, and an old‑school barber or two. Go on weekday afternoons for easy browsing; weekends draw aunties stocking up for ceremonies. Retro, photogenic, and very Bangkok 1990s—in the best way.
