CHAO MUNG DEN HA NOI!!
Despite the variety of street food available --- most places will serve only one or two dishes. If the person sitting next to you is eating something that looks appealing , just point at their meal and the job is done.
There is food being sold in every corner, and some of it is delicious and some not so... but don't be afraid to try.
Here are some photos I took while I was walking in Vietnam...
It seems that at some of the more popular street restaurants, customers will sacrifice themselves to get that tasty dish, even at the mercy of the road. I can completely understand that some foods are worth the risk!! Bread sellers plop their baked goods in the street for maximum exposure, forcing traffic to weave around them. In Vietnam... it's their way of life!!
