This has been my favorite restaurant for the last 4 years! I just love this place! It's pretty cheap, there is a huge selection of food (I'd say they have close to 100 dishes -- all vegan!) and almost everything I tried has been great (and I have tried a lot of stuff!).
I took my non-vegetarian parents to this place and at first they kep saying "We didn't immigrate to Canada to come to a place like this where we can't eat any meat. Let's go to a proper restaurant." As soon as they brought the food though, they just kept saying "Wow! This is really good food!" They've come here often and my father even takes out food to eat at work.
My personal favorites are the shrimp rolls, the duck apetizer, diced vegetables with cashewnut, sweet and sour chicken balls, the black sesame pudding, and the coconut shake. They are absolutely yummy! My parents loved the three kinds of mushroom in taro nest because it was both fancy looking and delicious. You can check out their online menu at http://www.bodeduyen.com. Note that "pork," "beef," etc. refer to "mock port," "mock beef," etc. Some of the coffee and shakes have condensed milk in them though.
Furthermore, the waiter (owner?), David, is always in and he is super nice! He is helpful and friendly without being pushy and he is very willing to answer questions about anything on the menu.
I often meet with people here because we can hear each other (they don't play annoying music like other places do), the atmosphere is comfortable, and it's never very busy. It's also open really late so you can come here for a late night dinner or yummy shake!
