HI. I was just in Ho Chi Minh. A lot of the people still call it Saigon. It's a city of motorbikes- there are many,many more motorbikes than there are cars. Food is excellent,the noodles especially,and you're never without a little bowl of their fish sauce,called nuoc mam.
You will enjoy shopping at Ben Than market,especially for fruits,textiles and sleepwear.
The most happening bar is Apocalypse Now. Try to arrive by 10,so you can get a table by the dance floor.
Some of the best sights are actually outside the city. The Cu Chi tunnels, where you will have a chance to fire a real AK-47, is a must-see. Take also a day trip to the Mekong River Delta, which is very relaxing.
