Truly, one of the best to be found is at Tartine Bakery. But they are a bit dark, not as light/golden as you might expect.
This bakery is a workspace for students at the SF Breadmaking Institute, the quality bar is very high and the cost is surprisingly affordable. . . a great option for you.
While the place is Japanese inspired don't be fooled, they have french pastries that are exquisite. . . the croissants are amazing!
I have definitely enjoyed some fresh croissants here (the owner used to bake at La Boulange). And just try resisting a bacon and onion croissant. I know, pure evil.
Croissant perfection! Find these at Local Mission Eatery, there's a bakesale on the sidewalk in front of the restaurant weekdays starting 7.45am or so.
Love Tartine's but here's two others to try. Castro Tarts - owned by a Vietnamese couple who trained in France - make big, buttery croissants. Celia Sack tweeted about them and I had to go. My favorite though comes from the new kid on the block, Will Werner of Tell Tale Preserves (Ferry Building farmers market: Tuesdays/Saturdays). Light, flaky, heavenly goodness.
No idea who makes their croissants (it may well be someone already on the list!), but they are awesome. Perfectly flaky on the outside, beautiful buttery layers on the inside.

get there early, they run out! you can also get them at the adjacent coffee kiosk called Vega (serving blue bottle).
recently enjoying the Java Beach croissant with Nutella - lightly warmed with extra powdered sugar on top. not sure who supplies their pastries but they are scrumptuous :)
