2 nights in NYC for Tiki Time!

I have two evenings in NYC (Manhattan) this week. Having checked Critiki I see that I have several options to visit. I am looking for recommendations, I can only do one a night due to work the next day! Recommendations? Thanks in advance

For tiki, top of the list should be PKNY (http://www.pk-ny.com/) and the nearby Lani Kai (http://lanikainy.com/). If you want to go a further north, there's Otto's Shrunken Head (http://www.ottosshrunkenhead.com/). Although not tiki, near Otto's are Mayahuel (http://mayahuelny.com/home.php) and Death + Company (http://deathandcompany.com/) which both serve world class cocktails.
