I'm not a dim sum fan by any means, but when in Toronto..
Luckily we landed on a weekday and headed straight to Dragon Boat about 15 minutes before it opened. We heard the wait can get intense so we were sure to be the first seating. They have a pretty extensive dim sum menu with all the basics as well as some foodie-esque fusion type dishes like foie gras & mushroom rolls, Japanese ramen in pumpkin soup, deep fried taro balls with quail egg, and turnip cake with ham and sesame.
We tried all of the standard dim sum dishes plus a few others and it was really good! Everything tasted freshly made with quality ingredients. Because we came in on a weekday, all the S/M/L dishes were discounted, but you have to pay with cash.
