It seems that there are not many places that you can go to find blue crabs in New Jersey. However, I did find a place that you may like, it is called: Blue Claw Seafood Restaurant and Crab House in Burlington, NJ. There, they have platters for around 40.00 as well as an all you can eat plate. The restaurant has gotten good and fair reviews so you will have to check it out and see how you like it.
