Fournee in Berkeley has what look like savoury kouign amann!
Yup, and it's delicious. The pastry texture is airy on the inside (as you'd expect from a croissant) and shatteringly crisp on the outside. It's so filling that I wasn't hungry for hours after eating it. The photo is a bit foreshortened: in real life it's more muffin-shaped, so a bit taller than a KA.
