Not sure how i missed this one til just now. Thanks to the tipoff from Trevor Block!
It's totally worth doing and i have strong conviction you will also be presented with free wine. Also because it's at the Abbotsford Convent you can enjoy a good (vego) donation buffet meal. Starts at 6 and you leave when you're done.
So to recap, do this tonight if you're looking for free wine and good art.
