Y Lan has been a family favorite of ours for a while. Each few weeks or so, we would go and enjoy traditional vietnamese food. Coming from a vietnamese background, this place really hits the spot.
There are many traditional plates served there, such as banh xeo (vietnamese crepe), cha ca (fried fish on dill), nem nuong (pork meatballs) and the list goes on.
The pho (soup) is very good as well. My personal favorites would be the bun bo hue (hue-style noodle soup), banh tom chien (shrimp on fried sweet potatoes) and their general tao chicken, which has an amazing sweet and sour combination.
The service is friendly and helpful when indecisive, the price is right, it's a BYOB and the food is great. For a traditional vietnamese meal, this is one of the best places in town and has a good location (walking distance from metro beaubien).
