But yes, be careful. I only ever got sick from the stomach 3-4 times in my life and ALL of them were after eating in Mexico City
Vietnamese cuisine has received some major street cred in recent memory (Anthony Bourdain's praise comes to mind), and a quick visit to Ho Chi Minh City's Ben Thanh or Binh Tay Markets explains why. Similar to the other Southeast Asian destinations listed, the street food in Saigon embraces a mix of cultures, primarily the city's French colonial background with Vietnamese spices and ingredients. In addition to Vietnamese standards of pho and bánh mě, some other notable dishes include com tam (cooked broken rice) with a fried egg on the top, Bo La Lot (seasoned beef in a leaf), and spring rolls. A member noted that no matter what Com tam dish you get, it will always be served with nuoc mam (fish sauce), and since each street food stall usually makes their own, people will often choose which stall to return to based on their nuoc mam. However, since hawker registration and street food health standards aren't as stringent in Vietnam, travellers should be careful to always choose popular, crowded stalls with high turnover.
