Local dishes include tapado, a seafood stew made from prawns, fish, and shellfish, seasoned with plantains, yucca, and coriander, and cooked in coconut milk. Tortillas de harina are flour tortillas stuffed with cheese, or anything else for that matter.
As for restaurants,
Safari (northern end of 5a Avenida, tel. 7948-0563, 10 a.m.–9 p.m.) is popular with locals for its large portions of excellent seafood dishes ($7–10) served in style on an open air, thatched-roofed platform over the sea. It also does excellent chicken and meat dishes ($4–6).
Another good seafood option is the restaurant at Hotel La Caribeña (4a Avenida between 10 and 11 Calles, tel. 7948-0384), known for its caldo de mariscos and tapado. For lighter fare, try the rice and beans.
For burgers, tortillas de harina and delicious fajitas, head to Pepín Burger (17 Calle between 8a and 9a Avenida, closed Tues.) in a second-floor terrace where you can catch the tropical breezes.
The only real coffee shop in town is El Cafecito (13 Calle between 6a and 7a Avenidas, 7:30 a.m.–11 p.m. Mon.–Sat.), where you can enjoy espresso beverages and pair them with tasty pastries and bagels.
