Museo de Chocolate
Not so much of a museum, more like a whole shop (or cafe) dedicated to chocolate. Bliss!
Delicious chocolates are made from chocolate beans grown in Baracoa, in the south of Cuba.
You may have to queue for a table, but it's worth it. Go in the morning when the queue appears to be shorter.
In a nod to the 'museo' name, there are several glass display cabinets with old cups of cocoa and chocolate ingredients.
