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 frequently praised the freshness and flavor of the seafood, particularly the oysters and various entrees.

I couldn't recommend a better oyster, fish, happy hour location in all of Denver, maybe even in the state and beyond. Super friendly staff and great recommendations as well. I already can't wait to come back.

We went for the NYE prix fixe. Dwayne, the chef, makes the best short ribs we’ve ever tasted. And our server Justin was the best. Can’t recommend it enough!

A decent place to stop in for a raw bar. None of the oysters blew me away. The Jax mule was very tasty. Price doesn't match up with food quality. If you are desperate for oysters, not a bad spot. If you expect great oysters, maybe look elsewhere.

Finding reliable, high-quality seafood in Denver can be a challenge, but Jax Fish and Oyster House consistently delivers! Every visit has been an absolute delight. The food is always incredibly fresh, beautifully prepared, and full of flavor. I’m especially a huge fan of the white wine mussels and oysters—they’re simply phenomenal, and the grilled bread? Amazing.
The staff is another highlight—always efficient, kind, and genuinely accommodating, making every visit feel effortless and welcoming. The atmosphere strikes the perfect balance between refined and relaxed, creating a dining experience that feels special without ever being pretentious.
If you’re looking for top-notch seafood in Denver with impeccable service and a warm, inviting setting, Jax is hands down the place to go. I’ve never had a bad experience, and I keep coming back for more!

Decent dinner option near Union Station in downtown Denver. The ambience was slightly less fancy than we expected for a date night out but the service was friendly and relatively quick. The oysters were delicious - definitely recommend doing a flight to try out multiple flavors. Portions are small and pricey but to be expected for a fish house.
