If your groom happens to have a sweet tooth, shopping for wedding cakes can be like taking a stroll through a candy store. Even if he's Team Pie, he won't find it too excruciating to sample delicious varieties of cake. Many upscale bakers offer free champagne during your tasting session, so you'll enjoy a little bubbly as you compare frostings and flavors.
Most grooms will be happy to get in on the cake selection just to make sure you don't choose something too crazy. They'll keep you focused on the practical aspects of the cake: Does it taste as good as it looks? Not many people will appreciate a traditional fondant, for instance. If you have your heart set on something exotic, let him have his own groom's cake -- just the way he likes it. And if you reach a complete impasse, there's always the option of cupcakes in multiple flavors.
