Ho Chi Minh City is a metropolis on the move – and we’re not just talking about the motorbikes that throng the streets. Saigon, as it’s known to all but city officials, is Vietnam at its most dizzying: a high-octane city of commerce and culture that has driven the whole country forward with its limitless energy. It is a living organism that breathes life and vitality into all who settle here, and visitors cannot help but be hauled along for the ride.
