Saigon is definitely one of most beautiful ciites in the World at night. At night, it is hard to tell the difference between Saigon and any other Western city.
(Saigon Centre located at the intersection of Le Loi and Pasteur)
(Casio neon sign near the Pho 2000 restaurant that Bill Clinton visited)
(The famous Samsung TV display near Pham Ngu Lao)
(Sorry, bad picture, this is near the bus station)
I believe Saigon has a pulse all its on at night. It is exciting, amazing, and unbelievable.
