After reading a great deal of the reviews here, I've come to the conclusion that people are looking for something Boudin isn't known for.
They are known for the best Sourdough in the city--THAT'S IT.
It's not a sandwich shop, it's not a pizzaria, it's not a Bagelry and it's not a chowder-house. They do not even specialize in customer service. While they do sell all of those items, It's a bakery that specializes in BREAD. That is the focus!
That being said, go there for that--Fantastic, Old-School San Francisco style sourdough. I grew up on the west coast and have had Seattle style sourdough, I lived in Alaska and had Alaskan sourdough, but my favorite has always been SF-Style sourdough, and this bakery does it perfectly. The wonderful, tart fragrance, the perfect crust and the slightly sweet, moist interior is why one goes to Boudin. So, get in line, place your order and get the hell out of the way for the next person. They want great bread as much as you do.
On a side note, get an extra loaf and have them slice it for you (free!), save it for the next day and make French Toast out of it, serve with salted butter and real Maple syrup. You will NOT regret getting that extra loaf! Quite literally the best French Toast I've ever had, hands down.
