2 Best Restaurants in Guanacaste and the Nicoya Peninsula, Costa Rica

This roadside grill is home to the country's best barbecued pork and beef, slow roasted for 16 to 18 hours over a wood fire and served with dynamite barbecue sauce. Sides go beyond coleslaw or fries to include lentils stewed with bacon and onions. If you've been tempted to try Costa Rican–style chicharrones, try them here—served with refried beans, local cheese, tortilla chips, and salsa. Beyond barbecue, there are imported beef steaks, plus a filet mignon smothered in mushroom sauce. If you can persuade any noncarnivore to enter the premises, the menu also has salads and fish. A playground keeps small children occupied while parents dig in. And there's a Pops ice-cream parlor attached to the restaurant.

The Tres Hermanas restrooms are the poshest and cleanest on the long stretch of highway between Puntarenas and Liberia.

El Lagarto serves up fresh, local seafood and high-quality meat, grilled to perfection on a massive, open-air, wood-fired barbecue. Sink your teeth into juicy tenderloin, lamb chops, mahimahi, prawns, tuna, mussels, chicken breast stuffed with mushrooms and cheese, portobello mushrooms, or a whole grilled lobster. You won't find any barbecue sauce here; everything is simply brushed with extra-virgin olive oil and seasoned with a bit of garlic, salt, and pepper to complement the flavor of the food. Dinners include grilled vegetables and potatoes; salad is à la carte. There's also a kids' menu, an ample wine list, and an extensive cocktail selection, not to mention banana splits. The restaurant is open for dinner only, though it opens at 3 pm for cocktails. Tax and service are not included on the menu prices, so expect to pay 25% more than advertised.
