WHAT RESTAURANT DO YOU THINK IS THE BEST by that I mean -- If you wanted to enjoy an excellent dinner in an elegant environment where your chica would be impressed, where would you go? 
Depends on the kind of food you enjoy - Typically, the chicas I know are more impressed more by how you take them out and treat them more so than where you take them (my limited experience).  Some of my best dinners with chicas have been in casual places.  That said -
In the SJO area - I like the Inka Grill (the one closest to San Pedro) - great food (ceviche, beef, seafood, etc.), for me better atmosphere than the one in Escazu.   For great atmosphere and a view, I like the Capitol Grill at the White House.    Alot of chicas like Fogo Brazil - for me it is very so so and way to expensive.   
In Jaco - my favorite is Tsunami Sushi - a bit pricey but great atmosphere and awesome sushi.
I am anxious to see other responses to this post as I am always looking for good dinner options.
Peace, love, and good dining for all,
