Lisbon's chocolate fair opened on Thursday at Campo Pequeno Square in the Portuguese capital, with dozens of local and international brands displaying tasty and unique cocoa products.

The hundreds of sweet-toothed visitors had plenty to choose from, including bonbons, macaroons, truffles and brigadeiros - a chocolate bonbon originating from Brazil.

"The concept we have created consists of brigadeiros with Portuguese flavors," said Vanessa Santos, manager at Brigo Doce.
