    This is my absolute favorite restaurant in Marathon. The food is always fantastic and no matter what I order I am always delighted with my meal! The sushi and tuna nachos are a must. Fresh fish every time. Wide variety of drinks and dishes. Amazing service and always efficient, happy and polite. Can’t wait to return and wouldn’t hesitate to recommend to anyone looking for somewhere delicious and welcoming in Marathon.

    We were seated right away. They were busy for a Sunday night. Service was prompt and our server, Brian, was attentive, knowledgeable and very helpful. We had the lumpia and tunachos for appetizers. The lumpia were authentic and delicious. The tunachos were out of this world. For our meals we had the hog fish with scallops and shrimp, the grouper matazlan style, and the shrimp Alfredo. My personal favorite was the grouper but everyone thoroughly enjoyed their meals and all very cooked perfectly. We finished with key lime pie and salted caramel cheesecake. Both were very good but the star was the cheesecake. The kitchen is fast, service was great, everything was fresh and tasty. Would definitely go back.

    Made reservations to eat outside by the water. It smelled and looked like we were in a third world country. Food was below average. Beyond disappointing. Michelle was an awesome server though.

Staff is some of the very best we have ever experienced. Definitely a favorite meal every time we visit the keys. Would highly recommend.

    We were celebrating our 21st anniversary. We loved the ambience of this restaurant, the food is exquisite and amazing and our experience was one the best because we had the best server ever. Casey went above and beyond our expectations and she made our time there unforgettable. Castaway is very lucky to have her, we definitely are coming back from Miami!!! She made the difference!!!

    A totally hidden gem. Very chill but warm vibe rustic and clean. Service attentive Morgan our waitress was excellent. Chef Bo came to our table to tell us what fish he just finished cleaning for the nights fresh catch. I had tile fish Wreckdiver style so delicious. Hubby had the awesome hogfish with the shrimp and scallop stuffing. Oh and we started off with the nominated best conch fritters. I’m not a conch fritters fan but these were very good not chewy at all. Topped off with the toasted coconut key lime pie.

    I grew up in Marathon and this is by far in e of my favorite restaurants in all of the keys. We had the tuna nachos and they were so good we ordered another. We snacked on some other apps and ordered crab Rangoon, calamari and buff and blue oysters. We shared the seven seas roll for dinner. There wasn’t anything we didn’t finish. For desert we had the peanut butter pie and the raspberry donut cheesecake. I’m. It usually a pie person but these were legit amazing. To top it off Casey our waitress was the best server I’ve had in many years. She truly loves her job and made the whole experience fun and enjoyable. Don’t miss eating here if you’re in town or a local. Ask for Casey you won’t regret it.

    Hole in the wall, but the menu is really diverse! Getting your fish entree cooked with an add-on is worth it! I did not, and my snapper was dry. However, my boyfriend got the Lionfish coconut fried and it was delicious! Bartender was not flexible with drink orders which was disappointing.

    All I can say is do not pass up on the lionfish if they have lion fish on the menu, get the lionfish. Probably the best piece of fish I have ever had cooked with lemon, butter and capers. It was delicious the coconut lionfish was fantastic as well!

    Highly recommended. Menu had something for everyone, great beers on tap, and the food was incredible. Best of all though is the service!!! Every waitress and waiter were pleasant but I’d have to say we had the best in Tammy. I travel the country a lot and do business dinners in all kinds of restaurants, but I’ve never had someone treat us as great as she did. 100% we will be back and if you go get the Lionfish!!!

    Don’t let the location deter you. It gets better once inside. Service and food was excellent. I had the snapper, wrecker style with no butter due to allergy. They accommodated my dairy allergy with no fuss. Snapper was delicious. Perfectly cooked and fresh. I would definitely return.
