The Nasty. I think Mighty1 was kidding about that one.
As for stripclubs....if you have not been to SJO, just a little warning. They can be expensive ripoffs. I am not sure why anybody would go to one, when the Blue Marlin is sitting right there where all the girls are there for the taking, and you are not being hit on for drinks and extra fees.
I admit I am not the most experienced on the boards on the stripclub scene, so maybe I am missing something. On my last trip I did visit the new Casablanca, which is down the street from the Blue Marlin and the Marazona. Very nice, clean place. They actually have nice bedrooms there right off the dancing stage. I heard it costs $70 bucks for an hour. The girls that night were in the 5-7 range.
If you become a VIP here you get a discount at Casablanca. Same for Josephines...although I have never been to that one.
