re: Good restaurants/breweries in the Jupiter, WPB, or Port St Lucie area.

Some good recommendations are already in this thread. Here are a few more:

Brass Ring Pub - even better food than the Thirsty Turtle that others have recommended
U-tiki - can be long wait for seating, but the beachside limited menu is great too
Hogsnappers
The Dive Bar
Little Moirs Food Shack
The Connection for Subs and Sandwiches - takeout only for now
Yardhouse is a chain, but pretty good beer, food and atmosphere
Calaveras Cantina is worth a try.
Tiki 52 in Tequesta for harborside
Sailfish Marina down in Palm Beach Shores
Two Drunken Goats, also Palm Beach Shores
PapiChulo
D'Angelo's Pizza and Italian in Palm Beach Gardens
Waterway Cafe
