Fresh seafood, beans, and rice are staples of the diet here. One of my favorite dishes in Costa Rica was the simple arroz con marisco — or rice with seafood. Ceviche is also very popular here.
You’ll also get plenty of fresh tropical fruit, which you should absolutely take advantage of – some varieties are hard to get in the states, and you’ll be pleasantly surprised how different they taste when they’re fresh. Costa Rica is also known for its coffee, so make sure you enjoy a cup…or three.
