After all day (or few days!:)) in museums it's good to rest a bit in Parque del Retiro. If you want to buy some presents for your friends or family (or just for yourself:), lots of shops are situated in Gran Via Street. The biggest department store in Madrid is El Corte Ingles (between Gran Via and Puerta del Sol).
If u are tired of shopping, go to a bar and eat spanish food - e.g. Paella or Tortilla de patatas or if you aren't so hungry take a sandwich with special spanish ham (bocadillo con jamon serrano). When you will be bored of MAdrid (but I know you won't!:-)) you can go to Toledo - it's a very beautiful city with gorgeus defensive walls and 'Alcazar'(Moorish palace, stronghold) in the center.
