When we went here, we arrived 30 minutes prior to opening and there was quite a long line; I think we waited almost 45 minutes. If you're into baked goods and pastries, it's worth the wait. I liked their banana cream pie but it's big!
Take the Ferry between Ferry Building downtown and Sausalito. In Sausaltio you have Le Garage, Sushi Ran, Heath Ceramics. In Ferry Building there are ton of great restaurants and artisanal food stalls (meats, cheeses, breads, coffee, etc)
Sloane will dig all the sights and sounds, even at her age. We got Tatum an awesome hat there that she plays with to this day. Makes for great pics too.
This place is gorgeous! They have an amazing array of plants and flowers and then, after you're done, you can have some delicious tea and look out at a koi pond.
