Shark-fin free dim sum in Vancouver or Richmond?

I'm trying to organize a small holiday get-together for a class, and we're hoping to enjoy some dim sum together. I'm a vegetarian, and content with the standard veggie options (rice roll with mushrooms/doughnut stick, fried sesame balls, steamed vegetable dumplings), but I can't stand the thought of supporting a place that serves shark fin (soup or otherwise).

I've done a ton of searching, and it looks like nearly every well-recommended spot (Kirin, Fisherman's Terrace, Pink Pearl, Sun Sui Wah, etc.) serves shark fin, at least according to this website: http://www.stopsharkfinning.net/boyco.... I've also tried scrolling through the recommendations on the boards and then downloading menus, but to no avail.

Does anyone know of a dim sum spot that refuses to serve shark fin products? Good vegetarian options and cart service are a plus, but a simple lack of shark torture will do!
