Review summary

AI-generated from verified diner reviews
Castaway Waterfront Restaurant & Sushi Bar in Marathon is a seafood lover's paradise. Revel in the "amazing sushi," "excellent food," and "friendly service" while enjoying the lively dockside atmosphere. "Don't miss" the lionfish dishes and lobster enchiladas. The "knowledgeable staff" and chance to spot manatees enhance the experience.

    Food, service and atmosphere have made this our favorite restaurant in the Keys. Plenty of good restaurants but Castaway is our choice when we want easy. Consistently great food and choices, very friendly staff. Highly recommend ⭐️⭐️⭐️⭐️⭐️

    We came for brunch after mass this past Sunday. We ate Benedict’s, blackened Pompano BLT, French Toast and Country Fried Steak and Eggs. All were perfectly prepared and tasty. Service was excellent and our coffee was served fresh and hot! We ate here on the first day of our vacation and plan to return before we leave. Do not miss this restaurant when visiting the Florida Keys.

    What a fun place to eat!! Having seen that Diners, Drive Ins, and Dives was here, as well as online reviews, we knew we had to try this establishment. We were not disappointed. Everything we ordered, from the smoked fish dip, to the fresh hogfish with shrimp and scallop stuffing, to the grilled lion fish, to the desserts.....wow...everything was delicious!! Table service was amazing. The place was rocking, yet our food came out timely and hot!! We actually went back for a second dinner during our stay in Marathon. I would recommend that you make a reservation if you plan on eating dinner here. On both nights, we arrived at our reservation time and were promptly seated. We will be back!!!!

    If in the middle Keys, Castaways is a must! It doesn’t look like much from the outside, but the food was amazing and the manatee visited around dusk! Try the crab queso and the lobster enchilada. You won’t be disappointed!

    Food, ambiance, and service great. Parking is absolutely horrible. Not sure how a business can run with no parking. Take an uber and you’re fine.

    Food was so good that we came twice on our trip. Both the sushi and seafood is worth stopping for.

    The lion fish sushi roll was great! So was the Blackened shrimp Alfredo. Securing reservations through open table earlier in the day was key. When we arrived for our 7:15 reservation there was 1.25 hour wait for those with no reservations.
