They still use a descendent of that same sourdough starter today.
Locals love it, too.
Creamy clam chowder served in a sourdough bowl is their most popular dish, and a favorite with shopgirls from Macy's and the Sephora cosmetics superstore in Union Square. But Boudin's got pizza, too, as well as croissants and chili, and a wide range of gourmet sandwiches. They'll pack up a loaf, to go, if you want. The caf is also a great place to just put up your feet, sip a caffe latte and do some serious people-watching.
