I have been going to Anh Dao for years and without a doubt this place has the best Nem Nuong in Toronto. I would often ask for extra rice paper & a little knife to slice my sausage in half (length wise). By doing this, I get more rolls & am able to use all of the vegetables that accompany it. I tried their sour soup & found it wasn't sour enough to my liking (Bun Saigon further south on Spadina makes the best soup).
Owned & operated by a nice family, the food there is truly authentic. Though high end restaurant is nice for special occasions. For 'everyday' eats, Anh Dao is on my short list.
BTW Susan C, I believe plantain is the fruit that you are looking for.
