After more than 18 years in the sandwich-making business, Michael's Sourdough Sandwiches opened its doors in Rohnert Park in 2010. With locations in San Rafael and Petaluma, Michael's Sourdough Sandwiches has brought its award-winning Old World Style sandwiches farther north. Its sandwiches earn their distinction due in part to sourdough bread, hand-prepared meats and secret family recipes. The shop prides itself on the use of all-natural ingredients with no sugar added. Online ordering and catering are available. Please check the company's Facebook page for updates.
