In the heart of the Red Light District is a small alley that leads to this charming oasis, "Blue on the Quay," complete with the innocent chirping of birds. Auspiciously set in a courtyard that once belonged to the Bethanienklooster monastery, this place offers a restful ambience with multiple dining areas (one is no-smoking), each with a unique and serene view. Original wood floors and exposed-brick walls hint at the building's 1625 origins, but white tablecloths, an extensive and inspired wine list, and an open kitchen that employs fresh local ingredients in its Mediterranean-influenced masterworks speak more of an unpretentious and contemporary take on chic. After starting on a foamy pea soup with chanterelle mushrooms and pancetta, you may want to indulge in a melt-in-the-mouth cod seductively smothered in a sauce of chorizo and fennel.
