Velvet is a Belgian owned cafe in Poblado, Medellin. Their specialty is, of course, chocolate! You can get very delicous hot chocolate and chocolate cake here, but coffee and sandwiches as well. The atmosphere is super relaxed, with jazz playing in the background. I found this the best spot to concentrate in El Poblado. There are power outlets at the bar and at the couch, so you can keep working longer than your battery lasts.
