Could not recommend this more highly. As someone who lives in Saigon, I have done a lot of touristy tours when I've had visitors and this one would be my all time favourite.
Anh was a great guide, and his staff were equally excellent. He speaks fluent English, he knows all of the best places in Saigon and shares all of those little parts of day-to-day life in Saigon that we miss as foreigners. He took us to several districts (3, 10, 5 and 4) for a truly local look at life. I especially loved 'di choi' at the local flower market and 'di nhau' at a BBQ place. Finishing the night with some phenomenal seafood too!
While I'm sure they'd appreciate more notice, they accepted my booking at lunch time for a dinner tour 4 hours later! They also catered to our vegetarian friend wonderfully, making sure she was full of delicious food at every stop and she never felt like her vegetarian option was playing second fiddle to the meat-eaters' food.
I love living here in Saigon, and when I have visitors I try to share a slice of the heart of Saigon - the part that I fell in love with.
Vespa A Go Go's tour was a true reflection of what its like to live and eat in Saigon. Do not miss.
