There are some sports bar/restaurants around Jupiter and West Palm named Duffy's that are actually pretty decent and pretty reasonable. Three or four locations. TV's showing games, etc.
There is also an "all you can eat" buffet place called The Carving Station along U.S. 1 just south of Northlake Blvd. It doesn't look like much but it is surprisingly good and quite a bargain. It's the kind of place you'd expect to run into Seinfeld's parents! But a hungry player can really chow down there for a fraction of usual restaurant prices. And you can get in and out quickly if you need to.
Or, if you're looking for the safe and familiar, there's a Cracker Barrel right off I-95 about 8-10 miles south of the stadium exit.
