My husband and I wanted some authentic Costa Rican food and we saw that Isaga had good reviews so we tried it out after attempting to go to Burro burrito which is currently closed for remodeling. We were very pleased with our food at Isaga. I got the shrimp ceviche ( they had about 5 different kinds of ceviche), be sure to ask for tortilla chips because it normally comes with saltine crackers. It was fantastic! My husband got the casado with steak and it was a HUGE portion! All of it was delicious and we would definitely recommend this place for some typical Costa Rican food! Our total bill for 2 beers, bottled water, and both meals was about $20. It is located on a side street. It isn't too far from a restaurant called Wahoos. It is on the North end of Jaco.
