Matadero is a contemporary creation center, a charming place to go at night to see the concerts and architectural lights. It always has an interesting program going on.
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.
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!
