Nam is an excellent Vietnamese restaurant at Leslie and 16th (South of 16th, on the west side of Leslie). They have traditional authentic Vietnamese dishes as well as other options with a flare of modern fusion.
Their banh mih's are delicious with the right amount of heat and baguettes stuffed with toppings.
I've had their rice plates (bun) with short ribs and it is delicious. The ribs have a nice charcoal singe to it that adds some crunch, while the flavours are distinct of the marinade. The rice has a bit of sauce on them as well, so that it isn't dry.
I also had their rice paper wraps that come with a lot of toppings to assemble yourself. You dip the wraps into the hot water then begin assembling with veggies and the selected meats.
Seating is limited so be sure to get there early for dinners, especially on weekends. The staff are helpful. However, in terms of Western etiquette I'd say they are sometimes unintentionally condescending because they seem to assume non-Vietnamese patrons don't know how to eat certain dishes. They are nice and as mentioned, very helpful in explaining. I don't find it to be an issue though I can see others misinterpreting their eagerness to help as being rude or curt.
