Yi Yuan is a very popular place for family dinner in the north of Bangkok. Decoration is simple and there are booths as well as tables. Parts of the walls have been unfinished for years at some places, and I think it doesn't look too nice.
The food is what you'd expect of Vietnamese food. We wrapped our naem niang with vegetables and its condiments with the free vegetables in the thin pancakes, always a treat. We also had the traditional noodle soup with pork (fer moo yoh), which was okay, and a crispy pancake wrap with vegetables and peanuts (banh xeo), which was better.
Service was attentive, but the food took quite a while to arrive. I wouldn't get out of my way for this one.
