On a rainy summer night (thunder! lightening!), we had very low expectations of getting a table at Balthazar's Keuken—mostly because something I read said that it was hard to get in. But there was a table, right in the back by the open kitchen, waiting for us. (The photo is of our view of the kitchen.)
They serve a fixed menu. First course was a platter of appetizers, including paprika-y sobressada on bread with fried sage, beautifully anchovy-laden fried artichokes, shrimp in sage butter, and smoked mussels. For the second course we had a choice of fish (they called it red bass, not sure what that is but it was great) or meat (veal in a hearty sauce). And dessert was fresh strawberries with mascarpone laced with ginger.
