Good Vietnamese food

I found Tin Vietnamese, a Vietnamese restaurant in San Francisco, for dinner. I was going to eat ramen but happened to find this restaurant on Google Maps. I ordered Bun Bo Hue (Spicy noodle), Canh Ga Chien (Crispy chicken wings), and Vietnamese style lemonade. Actually, this restaurant has a high rating or stars on a couple of restaurant review website, so my expectation was not low. It was actually good. When I leave, I saw a long line in front of the restaurant.
