We wanted to eat at a Viet restaurant (many chinese and locals knows that Viet food is really good in Paris) but really wouldn't know any since we are tourists, we went on tripadvisor and found this little place. As other reviewers talked about, the entry is tricky - you actually enter the restaurant through the kitchen! It is run by a Viet mother, with sons helping here and there, her son speaks fluent English and French serves us and is really great that he explains the French menu to us in English patiently. The price is really, really cheap (compare to other restaurants in Paris), and the food is fresh and traditionally good, no fusion concept, which is really refreshing for a change, if you know what I mean. Give it a try, you will know what I mean.
