One of my early priorities for the November 2010 trip... sample the banh bot chien near the City Star Hotel! Noodlepie says: "From what I can gather Banh bot chien is a fried savoury rice flour cake mashed up with an egg and served over a bed of shredded raddish with a smattering of spring onions and a soy sauce dip." I can't remember the price for banh bot chien near the service station on the way to the supermarket but I think it was around 10,000 Dong or 20,000 Dong. The Final Word reckoned it cost him between 10,000 and 15,000 Dong to eat, back in 2008. Keep in mind that inflation is high in Vietnam.
