Portobello Rd, London, UK
The World's Largest Antique MarketPortobello Road is a colorful stretch of shops and stalls selling bric-a-brac and antiques. Part trendy neighborhood, part flea market.
On Saturdays, thousands of people flock there for bargains. I recommend going on a weekday. You can have the place practically to yourself to mill around.
Grab fish-n-chips to go and find an authentic souvenir.
