I had the luck of visiting this wonderful place a while back and I have been dreaming of it ever since.. I am a voracious fan of dim sum and being vegan makes this difficult.. except here. I am still not sure if it was all just a wonderful dream, but as the other reviews would have it, maybe heaven IS a place on earth.
Puppy love aside, the food is excellent. Mock meats are their speciality - it makes for a fun, enjoyable experience instead of trying to weed through the menu in order to find something edible. Textures, tastes, quanities.. all excellent, the only downsides being it's location (though I'm sure to people in Markham, it's a lucky thing) and the prices making it a special occasion thing only. Both of these things are minor though as when I'm asked what the best food I've ever had was, I refer them to this little place.
Restaurant is clean, staff are fine and understand English; I went with a native speaker so that did help move things along faster but I doubt anyone else would have an issue with this.
I recommend Graceful Vegetarian very highly.
Cons: You might need a drive there
