You haven't truly been to Vietnam if you haven't experienced Hanoi traffic. At times it seems like people honk more they can breathe, and that there has to be more motorbikes than people. Besides the noisy vehicles, I found Hanoi to have the best street food such as Northern style Pho, and Bahn Mi. The best place in the Old Quarter is Bahn Mi 25. It's the perfect amount of western sandwich needs, with traditional BBQ pork and fresh Vietnamese veggies.

The traditional city of Vietnam. Things feel different here. After being to both Saigon (Ho Chi Minh) & Hanoi I can tell you this major city is different from it's two alternatives. Lanterns, Tailored Suites, and Beaches. The street food is also unreal, dishes like white rose dumplings, Cao Lao (noodle salad), and cheap Banh Mi, the city has a little bit of everything. Neighboring one hour from here is Da Nang - another beach city with large buildings that will make you feel like a Vietnamese Miami. Rent a bike to the top of monkey mountain for a peak at how the city looks from above. 

Last but not least is Saigon. Everyone will tell you district 1 is the best, however I am here to disagree. I was burnt out of the loud walking street and chaotic vibes that district 1 brought - nothing like Hanoi chaos, that I loved. Take a motorbike trip 15 minutes to Cholon in district 5, here you find large markets and very tasty dim sum. Alternatively district 2 offered the best local market I had seen in Vietnam, with western clothing quality at low cost. Overall a great city to visit if you do the research to see what the different districts offer.
