No need to pay $20 for a guide in Manuel Antonio
We were warned that we would miss on seeing monkeys and other wildlife while in the park if we didn't hire a guide to point them out. We found that while walking along the trails whenever we saw a group of people with a guide pointing at something we just stopped and looked along with them and took pictures
Imperial Beer...it's everywhere. Just drink it.
Actually, it's not a bad beer, and the taste seems to vary from bottle to bottle. There's also Bavaria which is pretty tasty. Most places have Corona, but at almost twice the price, and it's not like it tastes better than an Imperial.
Good local food
It's not really off the beaten path, but right by the beach in Manuel Antonio, next to some of the souvenir stands, is an outdoor restaurant that consists of some benches under a tarp. They cook up local fare with either fish, pork or chicken on an outdoor grill, along with vegetables and some fruit. This stuff was tasty. I believe it was about $5 or $6 for a decent size meal.
Follow your nose just before the park entrance.
Dining in an airplane
The restaurant is integrated in and around a Fairchild C-123 airplane. You can read more about the plane's story on the website below.
The restaurant offers dining with great sunset views and live music. Blackened mahi mahi
Great little mexican restaurant, open and well design. Good mexican food, good options, generous plate, good quality. Recommended for an inexpensive lunch. Mexican salad and burritos (although the meat was ground beef)
