Probably the best budget Pho in the city. They only take cash, the quality of service can kindly said to vary (although always polite), you are often crammed together with other groups on a busy night, and its decor is mildly depressing, but they perform where is really counts, good food. The varied crowd usually has a good energy for a fun place to grab a bite.
Don't go here if you want an elegant dining experience. Do go here for a place with an interesting character and damn good broth.
