Deli at the Petaluma Creamery. Yelpers say: "If you are passing through Petaluma and want the BEST sandwich you have ever eaten- stop here! The bread is fresh and the cheese is some of the best cheese I have ever had on a sandwich. Simple and delicious. You can even sit outside on a beautiful day and eat lunch at the tables out front. A very nice feature. My kids loved this place too."
