At our visit in Nha Trang (one week), we tried a couple of restaurants to compare. We found Nha Hang Yen´s to be our favourite when we wanted local food. Nha Hang Yen´s Restaurant is a cosy restaurant if you want to get away from the restaurants on the main street. The food is excellent and the service is good. The price level is good is also very attractive. You feel relaxed and not stressed as you can experience at more "commercial" restaurants. I can highly recommend it.
