The Castaway was originally built in 1951 and known for many years as a place to get beer and shrimp steamed in beer. After all, in 1951 there were many shrimp boats parked a stones throw from the restaurant and if you never met a shrimper, the you probably don’t know it but them boys can drink some beer.
In 1999 John sailed into Marathon, Florida ending a voyage that began in Los Angeles. He bought the restaurant and began a new adventure, oh yeah, he also quit his job, sailed the boat and moved to the fabulous Florida Keys.
Now decades later The Castaway is busy again but with an expanded menu featuring all the S’s. Seafood, Steaks, Sushi, and of course Spirits and as of today now serving 32 BEERS ON TAP. Seating is indoor and outdoor on the water and service includes breakfast, lunch and dinner 5 days a week.

What People are Saying

“Saw Manatees!!!”
“We had two amazing meals here. Killer sushi. The staff, especially Tami, could not have been more kind and welcoming. Saw a bunch of manatees out back, which was really cool. Great food and good vibes.”

“Very Laid-Back”
“A local Marathon resident recommended Castaway to us…. And we’re glad we went. They ordered the conch fritter appetizer, blackened chicken Caesar salad, snapper sandwich and multiple slices of key lime pie. The food was excellent and came out piping hot.”

“We’ve eaten at Castaways twice. Once for happy hour, and then for breakfast. Both times the food was very good. Who doesn’t love inexpensive hot wings? Breakfast was also terrific. I recommend their house made sausage patties. Strong coffee!”
