I would like to recommend Sagasta 28. The foods, the service, the atmosphere, everything is first class there and you can have a lovely time there.

Chocolateria San Gines is the place people call the best churros and hot chocolate place. It was started in 1894 and the oldest and the most famous Chocolatería in Madrid.
When you visit Spain, paella is a must, isn't it? I recommend Les Quinze Nits to those who would like to have the traditional Spanish cuisine at the reasonable price.
