Was seated outside immediately next to an old catamaran. Not the view we were seeking. Sushi rolls were average. Fell apart and were a bit overloaded.

Simple blackened cobia was tasty. Steamed veggies were also as advertised, not drenched in butter.

Surprisingly, the happy hour chix wings were our favorite, although we were going for the seafood.

Would say there are better options before Castaways.

The sushi was amazing. I ordered the hog fish, which was way to salty. Service was very good.

Miso soup was terrible and the scallop/shrimp stuffed lobster tail was just all chopped up and creamy

Water view was a sail boat view that was moored next to our table. Gnats bothered us throughout the meal. Food was okay. Service was good.

We have eaten there before, it was excellent .
Also, the service was very good.
This last time was not as great.
The drink order was slow, the food was fried and over cooked and dry.
The drinks were good.
I went there originally as I am a veteran like the owner and I like to support all veterans,
I am not sure I will go back.

As always the food was great. We highly recommend the Tunachos on the happy hour menu. Our server Scotty excellently timed the various parts of our order so that everything arrived hot. The happy hour drinks were not watered down like some of the other popular places down here. The only negative was something that they had no control over, the no-see-ums were out and we sat outside so we go bit up. We still plan to go back.

As I was eating my meal the waitresses kept banging into my arm. The Seating is too tight. The sushi was excellent but my husbands grilled chicken was dry and boring.

Eclectic. Laid back. At first I thought we were in the wrong place. The area around feels a bit dodgy. The food excellent. Service great. We will be back. This restaurant is at a marina. So very much like the keys... not fancy.

Great, friendly service from Janelle. Food was a little pricey for the moderate quality. Fish tacos were good, but taste like any other fish taco, the Mahi sandwich wasn’t great, the sushi was very good.

First off, we LOVE Castaways. We have never had a bad experience in either food or service. Last night was no exception. Our server (whose name I unfortunately did not get, but she wears a mask with her own slightly enlarged and very pretty smile) was exceptional. While going through sides she highly recommended some of the potato sides, which we would have loved but are doing low-carb. We mentioned this conversationally, and she was beyond sweet and helpful. 1) she gave us recs for low carb bread and 2) didn’t even tempt us with the delicious rolls and ensured our salads didn’t have croutons. She was attentive, fun, and just sweet all around. The food was great (peel and eat shrimp, mahi mezatlan style, and scallops wreck diver style). Another great experience and we’ll definitely be back!

Seating was easy with a reservation. Sushi was good. However the service was a bit cranky. Disappointed with beer selection bc out of most every tap. 6:30 at night so what’s up with that!?!?
beer was highlighted on website so that’s a big reason why I went. Maybe call before you go if you want to be sure.

New Year’s Day breakfast with out of town guests. Service was great. Breakfast was inventive and great. Several eggs Benedict options But the regular options were available. Sat on the water side and had a lovely breakfast to start the year.

Loved everything about this place, made to feel very welcome by the staff and had a long chat with the owner who (because I have the same name as the frontman of one of his favorite bands) had been anxious to meet me. There may have been a bit of dissapointment as I wasn’t who he had hoped, but that didn’t affect the service or quality of the food which was all excellent. I can’t wait to be back in Marathon so I can eat here again.

We had dinner on NYE at Castaways. The drinks were delicious! The crab cheese dip was delicious! The baked oysters were also delicious! The lobster bisque was just okay. However, the sushi was subpar and super salty. I couldn’t eat mine and the rest of my party did not eat theirs either. We had a great waitress who took my sushi off of the bill. We had a fun time at the restaurant. Like I said, the wait staff was very attentive. Would go back for drinks and apps but would avoid the salty sushi!!

Vacation with kids and grandkids!
We all loved it. Especially the sushi. My son lived in Japan a while so he’s the expert! He loved it. And they all loved the Castaway Roll and the Mexican Roll. It was the most unique thing he’d ever eaten.
The tuna appetizers were awesome too.

They all wanted to go back again but sadly it was our last night in town.

Hopefully we’ll get to go back sometime!

We had a reservation for an outdoor table when it started to rain we decided to sit at the bar because they didn't accommodate for the rain. Otherwise great food the waitresses we had were kind felt like the hostess was rude and felt very overwhelmed and had been overbooked

Family vacationing together, out for an evening celebrating our nieces birthday. We had reservations which they were ready for....31 people at multiple tables. They did a great job at managing the group. The food and service was great. There was a variety of food ordered and everyone enjoyed.

Took about 15 minutes for a waitress to come over, but once she did, she was really nice and attentive. The food was only so so. We got shrimp and grits and different nigiri and sushi rolls. Nigiri was very thick cuts of fish which wasn't the best. They were out of the lionfish which we had wanted to try. Seating was too close together for Covid protocols and staff was constantly messing with their masks or not wearing them at all. We might go back for apps and drinks as they had a good selection and atmosphere.

We were disappointed by our experience here. We’ve eaten out everyday that we’ve been in Marathon and this was probably the least appealing experience. Service was friendly but very, very slow. Food was meh. The oysters Flagler were okay and the fresh tuna in the poke was delicious but it was overpowered by too much soy sauce. Ironically, for a fish restaurant, the highlight of the meal was my daughter’s chicken Mazatlan (ask for sauce on the side or light sauce) and the complimentary yum yum buns at the end of the meal. Ambiance out back on the water was lacking too.
