I had breakfast here for two days. I ordered pretty basic Costa Rican food - eggs, rice and beans (pinto), coffee with milk, etc. The service was very good, prices were reasonable, and it's a nice place to sit. - corner location. It is very centrally located in the heart of Quepos.
The dinner menu looks more interesting, and a little more expensive, but I would give it a try on another trip to Quepos.
