Seaside Park Jersey shore eats--if any
There are several places right by the entrance to Island Beach. Bum Rogers is my favorite, with a big bar to sit at during the day over beer and mussels. Big seafood menu, although i find the way the dishes are made varies from year-to-year based on who's in the kitchen. It's still a favorite though, and it's been there forever.
Berkeley Seafood has a takeout downstairs if you want fried/steamed seafood platters or lobsters to take home. They have a more formal restaurant upstairs. They've also been around a long time, although I heard they may be closing after this season. Pretty soon it'll be condos everywhere and nothing to eat.
Ebby's deli has an al fresco restaurant attached to it with dishes that are supposed to be pretty good. I've never eaten there though, since i usually go to one of the above.
Then of course, you're a short distance from Seaside Heights, Lavalette, Ortley, Toms River, etc.
