Good place to go for a quick healthy lunch or dinner, you can choose from a variety of paleo, vegan and vegetarian dishes. They also have a great organic coffee too!
After long hours at Reina Sofia museum time for going to Outer Space. It's called NuBel and it makes you wonderfully dizzy. Or, better, go there just before the museum - drink some wine and go to admire Guernica in 3D.
Going out in Chueca, the gay neighborhood of Madrid and grab a beer in the bars around is fun. One of my favorite programs is going to tranvestite´s concerts there.
A piece of Egypt in the city centre. This temple, a gift from the Egyptian government, was taken stone by stone from the valley flooded when the Aswan Dam was built. It’s a great place for a picnic in the summer. You can enjoy the sunset and the (grey) skyline of Madrid.
