If you've ever wondered where the excellent gastronomic offerings of the Pierre Boulez Saal come from, wonder no more.  The caterer is the restaurant Casalot, site of our next restaurant outing.  Whether traditional lamb or fish dishes, or one of the many vegetarian offerings, this Arabic restaurant has something for everyone.  The portions are huge, and come perfumed with the exotic spices of the Orient.  The drinks menu includes wines from Lebanon and Europe, German beer, and some spectacular fresh lemonades.  Just off Friedrichstraße, opposite the Friedrichstadt Palast (U-Bahn Oranienburger Tor).
