I go there a couple of times a month on business. Not sure what you're looking for.
I primarily hit the good chain restaurants when I am in the area, but there are a couple of places right on the water near Palm Beach Gardens that are cool tiki bar sort of places. (I-95 south to PGA Boulevard, PGA east past the big mall. Places are on either side of the intercoastal before you get to US-1.) There are some nice outdoor restaurant/bars if you go WEST on PGA, down on the left.
If I have time, I ride down to the Kennel club and log some time in the poker room. Not a ton to do in that area, but I seem to have a good time when I go.
