Saigon is the city that made Vietnam grow on me. For some reason my original post on this was deleted so this probably won't be as strong a post as it should be.
I had a great time in Saigon from the rooftop bars, motorcycle traffic again, the French buildings, and the East meets West fusion. I would see the Reunification Palace which was the last stronghold of the democratic South Vietnamese army, the Cu Chi Tunnels of the skilled Vietcong, and the War Remnants Museum (where the American war's atrocities are seen next to the "kind" treatment of American soldiers, though John McCain will tell you that his time in the Hanoi prison was anything but). The latter two were done on 4th of July as I also got to shoot an AK-47 which overall made for a fairly un-American celebration. I would also be driven by ladies in ao yais (traditional Vietnamese clothing) around parts of Saigon, including a more affluent place where rich people spent their money on empty apartments for money pools.
Food wise I went to my 3rd cooking class with Chef Tan who drove me on her motorcycle, cooked with me and picked ingredients from an organic garden. I had a great time with it overall. We made Banh Mi (the best I've ever had), Chah Cuan (a sour soup from Southern Vietnam), Papaya salad (I'm obsessed with it), and mung bean dessert. The food here is top notch and healthy, it can not be overstated.
Lastly, the people and country began to grow on me at this point. Saigon is a quirky place with a lot of fun. Whether it's the motorcycle traffic or the Vietcong dressed coffee chain servers, Saigon stays with you.
