We drove out of the way to visit Castaways again. The pricing is very fair and the food and service is great. . I have been there a few times and would definitely recommend it. It is not super fancy but it you want a low key place w good beer and great seafood then give it a shot

The fish was fresh and tasty. The service attentive and pleasant. Not fond of the sushi rolls because they were not tightly wrapped and had too much rice. Stick to the poke, the sashimi salad or get seared tuna over a salad. You will get the fresh fish and not have to deal with all that rice. One exception, the... More

We specifically ate here to try the lionfish. The menu is fairly confusing so you end up being directed by the waitress (who was not very attentive even though they weren't busy). Since the lionfish meal was $40, my wife had a salad with Mahi. It was overpriced for romaine lettuce and not so good Mahi. The lionfish was very... More

Amazing place amazing atmosphere!! Waited 2 years to try lion fish and this is the place to go. Also the menu has so many awsome choices for sushi, drinks, and different types of foods and I love the way the menu is worded makes a really fun time.

My family and I visited Castaway's three nights in a row and we had Melissa every night.. We couldn't have asked for a better experience, food, or server! We may be coming back for a fourth night! Will definitely recommend this place to friends and family..

Huge selection & usually very good! I think we ate here 4 times on this last trip. Our friend got a steak that looked awesome! My husband likes their fried shrimp. I am gluten free & try different seafood dishes that are usually better than average.

Tucked away at the end of 15th Street, ignore the shady neighborhood on the way in - it's safe, promise. Authentic sushi rice made in a traditional bamboo steamer. Co-owner Arlene prepares the sushi for lunch daily, so I recommend stopping by at lunchtime rather than dinner. I love their Nigiri (salmon, tuna, hamachi, Ikura - they have all the... More

The food was good, but a little expensive. One person ordered wings, another ordered conch fritters and my husband ordered the mahi sandwich. I ordered from the sushi menu. Everyone's food came out except mine. By the time my food came, everyone had finished their meal. The manager was not extremely professional, but at least offered me a free dessert.

Thank you tripadviser for this find. Pulled in looked around then saw the opening no real door step in to the patio. We made reservations prior and went straight to our table. Our server was very good, very attentive and helpful. Wife had the coconut snapper, large portions, very good. I had the petite sirlion and crab stuffed shrimp, excellent.... More
