Bangkok is awesome. Pad thai, ping pong balls, reclining buddhas. But nowhere is sweeter than this hidden corridor of Central World Mall, where crowds of high school kids practice their sweet dance moves every weekend. Each gang brings their own routines and own MP3 players. Any reflective surface–shop windows, aluminum panelling, fire extinguisher cabinetry–stands in for a mirror. And the moves? OMG. It’s pure coordinated secret wonderfulness. Justin Bieber, eat your heart out.
