There is a street near downtown where there are vendors, called las changueras, i.e. the shrimp ladies, that sell raw shrimp by the kilo to people. &bnsp;These are fresh shrimp fresh (actually fresh frozen) off the shrimp boats. You can buy the shrimp and take it home, or take it to a restaurant to cook it up for you. There are 2 restaurants within one block: ??? and Mariscos Dunia that will cook it up for you.
