Savory croissants?

Here we have an heirloom tomato one from Radio Bakery, a potato-ranch one from Welcome Home, and a brie-garlic-artichoke one from Claude (formerly the old-school Patisserie Claude, RIP).

I know some pastries of this type are seasonal, but, all the same, what are some bakeries or coffee shops that are known for doing good savory croissants?
