Pho is the Vietnamese national dish that is normally eaten for breakfast. It consists of noodles with beef and vegetables in a steamy broth; it's that last element that makes or breaks the dish. Though it can be found on every street corner, someone had the bright idea of 'McDonaldizing' this dish and offering it in a clean hygienic environment. The idea was so successful that you're bound to spot Pho 24 outlets wherever you go, and they're a great way to fill up quickly without worrying about levels of hygiene. It may not be the tastiest pho in the country, but it's certainly passable and reasonably cheap. And by the way, despite the name, they're not open 24 hours.
