A restaurant in Costa Rica that offers lunches, dinners and parties for four-legged customers proposes an innovative concept: 'human-friendly'. At 'El Perrazo', dogs are the customers served by waiters and their owners are mere accompaniers. This is a breakthrough in the trend of 'pet-friendly' restaurants, which allow customers to be accompanied by their pets. It is a "dog-free-access place to play and enjoy in playground areas," says the owner of the restaurant Ruben Rodriguez, "people are just the guest." IMAGES AND SOUNDBITES
