We don’t take ourselves too seriously at Jax Fish House. Two things we do take seriously? The freshness and sustainability of our seafood. You know fresh fish when you see, smell, and taste it—and thanks to modern delivery technology, we bring in that freshy-fresh seven days a week.
Sustainability is a little more complicated. Not all commercial fisheries are created equal. That’s why we work closely with our suppliers and science-based organizations to ensure that every single thing we serve is responsibly sourced. We consider the stocks of the species we source to prevent overfishing and we work with suppliers who harvest in ways that have minimal impacts on marine environments.
Customers consistently praised the freshness and flavor of the seafood, particularly the oysters, mussels, and calamari.

Great place for happy hour or dinner, always busy, so getting a seat at the bar can be a challenge.

Some of the best prepared mussles we've ever had! We had the chorizo version. Our waitress was lovely. A perfect mix of engagement and letting us eat. She also avoided what many current wait staff do. She didn't walk up to the table already talking, which interrupts conversations or makes us miss the first part of what is said.
