Hanoi Old Quarter (Vietnam). 'Get agreeably lost in the city’s centuries-old Old Quarter, a frantic commercial labyrinth where echoes of the past are filtered and framed by a thoroughly 21st-century energy. Discover Vietnam’s culinary flavours and aromas at street level, perched on a tiny chair eating iconic Hanoi dishes like pho bo, bun cha and banh cuon.' http://www.lonelyplanet.com/vietnam/hanoi
