If you walk around cities in Thailand at 9-10 pm don't be scared that you will be left with hunger! It's very usual that there are street vendors everywhere especially at night! More shockingly a lot of those street vendors are actually franchisees. There's one brand of street vendors that everybody in Thailand recognize, with the combination colour of red and yellow it stands out at night. " Chai See Ba Me Kiow" is probably the most well known Thai franchise within the country and there has to be one in at least every small parts of town! Ba Me Kiow is basically egg noodles with some dumplings and soup, even though eating a bowl of noodles at night might sound too heavy for some but they are actually not that heavy because of the clear soup! Like I have mentioned because it's a franchise branches I can't pinpoint for you where they are exactly but if you are in Thailand you can just ask the locals at night about where you can find a good bowl of Ba Me Kiow ! I personally love this dish and brand because the price is only $1 and they usually open from 7pm onward so after my classes at the university I would eat a bowl before going back to my room and get the studying done!
