We are forever thankful to the capital for pho, but there are other tasty teasers in the north. Banh cuon (rice crepe rolls; wafer thin rice paper sheets that contain chopped pork,fried garlic,chopped mushrooms and a side of herbs and salad) are produced everywhere in Vietnam,but those that are made in Hanoi have dpecial characteristics,with wrapping as thin as a cheet of paper: In Hanoi there is an oc (snail) living in pond s and lakes that grows to the size of a golf ball, has a streaked colour and, while chewy, is very tasty.
