I have eaten in many different restaurants in Viet Nam, from local to high class restaurants just for the very simple reason, to find out about the food and for my blog. I realized that there are differences between Hanoi, where I am living now, and the south. In a high class restaurant in Ho Chi Minh City, it’s more expensive than in Hanoi, even though the food is about the same quality. Maybe we are paying more for better service? Another difference is that in Ho Chi Minh City they charge a 5% service charge in most restaurants, which is not very popular in Ha Noi, except in 5 star hotels.
I love to try all styles and I love to eat food all around Viet Nam. The only things that I really care about are service and staff behavior. The hygiene is not really a problem for me - I'm probably immune! - but I'm fond of clean places, on the street or wherever, and a comfortable seat. In Hanoi, I usually eat out at small places and most of them are stalls on the streets and in markets where you get the best food for not much money.
