4 Best Restaurants in The Osa Peninsula and the South Pacific, Costa Rica

Fabulous fish burritos, steak with tropical sauce, and a savory fillet of sea bass with a smoky jalapeño cream sauce are a few of the delights at this screened-in-porch restaurant in a bright-yellow clapboard cottage on the beach. Chicken or fish curry is popular with the locals. Attention is paid to sides, too, including creamy mashed potatoes, cheese-topped toasted garlic bread, and perfectly cooked vegetables. Beer and wine by the glass or bottle are available. Service here is with a smile, and everything is cooked to order, so relax—you're at the beach. If you want to try the banana pancakes at breakfast, consider staying at one of the four beachfront cabins, or just come along at breakfast time, 7 to 10 am. Bikes and boards can be rented here as well. 

Beer-battered onion rings, fresh hand-cut fries, and fried pickles have taken Dominical by storm at this laid-back alfresco kiosk in the Pueblo del Río complex on the riverfront. The fish tacos are outstanding—crispy beer-battered fish fillets accompanied by guacamole, red cabbage, and a spicy sauce are folded into a thin soft tortilla. You can substitute fried shrimp or go vegetarian with black beans and vegetables. The tortillas even come in a gluten-free version. Ultra-healthy grilled fish and vegetables are also on the menu, along with less healthy but delicious classic fish-and-chips. Beer, sodas, and fruit smoothies wash it all down. Seating is at wooden benches and tables on a covered wood patio.

If you want to enjoy a little local atmosphere, join the anglers, families, and backpackers at this tiny restaurant that has spilled over into a large waterfront garden. You can spend $9 for a plate of grilled fish or $36 on lobster. The menu is truly vast, with more than 50 platos fuertes (main courses) that run the gamut from seafood rice to whole lobsters to sirloin steaks. Wash it down with the only draft beer served in town, including microbrews, and gaze out at the Golfo Dulce. Marking the center of the dining area is a massive tree growing through the rafters. An added bonus: there's free Wi-Fi.

This pleasant terrace restaurant jutting out over the water has the best harbor view in Golfito, along with jaunty nautical decor and the coolest breezes in town. The seafood-heavy lineup includes grilled whole fish served in a variety of ways, including Caribbean style with coconut milk and a side of patacones (fried, mashed plantain). Tuna carpaccio and occasional sushi specials add a touch of sophistication. For a light lunch, the fish tacos are standouts—plenty of perfectly breaded and lightly fried fish plus fresh slaw and crispy calamari tossed on top. Salads are also on the menu, along with a few vegetarian dishes. The bar is a great place to hang out, particularly during televised sports events when fans gather to watch the two large flat-screen TVs. Grab a bucket of six beers for $12 all day long. Inexpensive, motel-style rooms and larger suites with the same view are available for rent.
