This is a really good idea. I am currently planning my San Francisco Wedding and I know there will be a few vegan guests, and I want to make sure they are accommodated. I think I will do a normal cake, and have additional vegan cupcakes for the vegans in the crowd. Great idea! Thanks for the advice. I went to a couple Weddings Las Vegas that did not have great choices for vegan guests, and it was a big bummer, so I will try to be as accomodating as possible.
