Neighbor Bakery: My vote for SF's best croissant
I've tried Neighbor's croissants a few times now--they are sold at Four Barrel, Sightglass, and Cafe Sophie (which doesn't get included among coffee heavy-hitters, but sells excellent, well-prepared Verve coffee in the Castro).
All the plain croissants I've had from Neighbor have been great--consistently so--with a beautiful crust, clean buttery interior, and a texture that hits the right balance between flaky and chewy. The other croissants I've tried in San Francisco have been either inconsistently excellent (Thoroughbread, Philiipe) or consistently bad (Boulange de ________).
Neighbor also bakes a pistachio and jam croissant and a pain au chocolat, but I keep returning to the basic butter croissant because its simple excellence stands out. The baker used to work at Tell Tale Preserve and Spruce, according to this article: http://www.sfweekly.com/2012-03-07/re...
