    We had a wonderful time. Get the lionfish. Not only is it vey good, but you are helping the ecosystem. Service was next level. Parking can be a challenge, just follow the signs.

    A wonderful surprise hidden in the docks of Marathon. The only caution is that parking can be an issue.

    We really enjoyed our dinner. We ate a lot of seafood on our visit, and we both agreed this was the best. Excellent house salads. Shared a lobster/crab sushi roll. Husband had blackened mahi; I had lobster enchiladas with an amazing homemade poblano sauce. Expected something creamy and was pleasantly surprised to see a verde sauce. Yum!

    Ordered Mahi Oscar style. Mahi was obviously previously frozen, watery, still slightly cold and tough. Baked potato small and tough. Service was fine although she forgot my caesar salad, so had to eat with entree. Really quite disappointed, especially for the cost.

    I absolutely recommend this place. All of the staff were extremely friendly. The food was amazing. Lobster Enchiladas were unreal. We also got to see the manatee in the canal by the outdoor seating. I guess they are always around. If you are in Marathon, you have to check this place out. Oh yea, good beer list too.

    Ottimo sushi 🍣 ma anche la Bowl e il tonno tataki erano ottimi. Atmosfera molto carina. Buone le birre locali e molto cordiale il servizio. Consigliato
