For incredible seafood tacos in New Jersey, look no further than Fat Fish Taco, a cozy restaurant in Caldwell. With so many options to choose from, including grilled mahi-mahi, spicy shrimp, and pork belly, you're spoiled for choice. However, many customers suggest going straight for the blackened fish tacos. They're hot but perfectly balanced, topped with cooling crema, crunchy cabbage, chipotle aioli, and pico de gallo.
