Atomium, Camden Stables Market
There's no shortage of fun bric-a-brac and antique finds at most markets, but Atomium won us over to its genuinely cool wares (we spied everything from vintage Kenzo to a '60s-era Pirelli calendar to couture bags and first-edition novels) and an owner who is enthusiastic, happy to let you poke around, and quick to tell you if said Kenzo design is too big for you. Head to Unit D18 at the Camden Stables Market on Chalk Farm Road on Thursday through Friday (11 a.m. to 5:30 p.m.) and Saturday through Sunday (11 a.m. to 6 p.m.).
