I don't have personal experience with this bakery but it's come up on several searches for 'vegan wedding cake Columbus' and is listed on the about.com vegan wedding cake page as well as reviewed by others. According to one review:
"Le Gateau pastry chef Sue Larson is the winner of gold and silver medals for her wedding cakes and sugar sculptures at the Societe Culinaire Philanthropique Competition, and is one of only three women voted into the oldest culinary society in New York the Chefs de Cuisine Association of America Inc. The Le Gateau bakery offers logo bakery items for corporate events, special occasion edible art gumpaste and pastries, and intricate sugar art decorated wedding cakes, with vegan options available."
