One of this fine restaurant's advantages is that it's open late -- its kitchen still takes orders when chefs at many other Amsterdam restaurants are tucked up in bed. This would not count for much, of course, if the food weren't good, but De Knijp is definitely worth staying up for, or worth stopping by for after a performance at the nearby Concertgebouw; many concertgoers and assorted other late-nighters do so. The menu is not wildly inventive, the standard offerings being something like oysters, grilled lamb, or roast duck, but you might find a few adventurous items, such as carpaccio with pesto, poached salmon with tarragon sauce, and goose breast with pink pepper sauce. Service is friendly, if sometimes a tad worn-out (this is a hardworking place) in this intimate bi-level bistro with lots of wood furnishings. In summer, a sidewalk terrace is available.
