El Jardín Secreto is a enchanted place in Madrid. They're specialized in teas, coffee and chocolate. You can have pies, suffles, hot chocolate... and everything is delicious. Their food have names like "chocolate orgasm" or "Death by chocolate". Not everything is about chocolate, though.
Decoration is unique: little lights (like christmas ones), quiet music, antiques.. Very romantic.
I recommend to call for a reservation. Otherwise you'll probably have to wait.
