I know this is a Pa. message board, but I was curious where you like to dine when heading to the NJ beaches.
Some of my faves are:
410 Bank Street/Cape May - Expensive, they stuff you in like sardines, but the food is just unreal!
Kipper'Z/Avalon - A newer restaurant on the circle in Avalon. Simple dishes with simple presentations, which is really refreshing in this age of the "garnish"
Big Bertha's Memphis BBQ/Wildwood - Great dry ribs! Definitely a casual night out, good place to bring the kids! Live blues on the weekends.
