This is a great place to visit if you're from out of town. There are a variety of beautiful Missions all along the California coast (a great one in Santa Barbara), but this is a beautiful church as well. They hold weddings here and it's a great setting for that special day. You do have to be aware that whether you are getting married or attending service that tourists are often peeking their heads in to see the church.
PROS: Location, beauty.
