We just went to the fish market and the fish was super fresh. The cashier was nice and helpful.

I bypassed the Lobster Ruben, had the conch ceviche and a fried hogfish sandwich, it was one of the best seafood meals of my life. Bonus points for the bar next door, and having the tartar/cocktail sauce readily available. Their prices are incredibly low for the freshness and quality they serve up. I can't wait to return to the Florida Keys again to eat here. read more

It's a bit touristy, but I'm a perpetual tourist. I take every friend there when I sail down and back through the keys. It's always a favorite. Bartenders are cool. They are used to dealing with people from everywhere. The food is a bit pricy but solid for Keys Seafood Bar Food! We usually sit up on the deck (adults only) and order a few apps from their menu and then a few dishes from the actual restaurant. Kids are welcome. You can buy fish food to feed tarpon. Just have to eat downstairs. Weekends are busy. Plenty of parking. Sometimes they have live music. Sometimes they don't. On the weekends it can get busy. But plenty of seating and moves fast! read more

Reading the other reviews, I was expecting something GREAT... so disappointed. I had the Lobster Ruben - boring sandwich. My wife had the blackened grouper sandwich and had the same opinion. Overpriced for a mediocre sandwich. It might be 5 stars for The Keys, but nowhere else. read more

Apple Maps says they open at 9 but it's actually 11 so had to wait a bit, got there at 10:30. Went for the lobster Reuben I saw all over tiktok. Really disappointing. There was a ton of lobster but it had no flavor at all. The sauce was good but there was very little of it. Fries had a weird aftertaste. At least the key lime pie was very good. Cute area to walk around. read more

My wife and I visited my brother in Highland Beach FL, then drove to Key West. On the way we stopped for lunch at Keys Fisheries. I was dying for grouper so I ordered the Reuben Grouper sandwich. My wife ordered a shrimp with rice bowl. I turned out that they gave me a lobster reuben at the grouper price. It was delicious. Fries were golden brown and tasty. My wife enjoyed the shrimp bowl. read more

Keys Fisheries - Seafood Markets Near Me - Marathon, Florida

Checked out Keys Fisheries -- definitely a solid laid-back spot to kick back by the water and grab a bite. Order at the window, find yourself a seat, and just enjoy the view. Hard to beat that kind of vibe. Food-wise: Conch fritters -- 7/10. Good flavor, nice bite, definitely enjoyable. Coconut shrimp -- 6/10. Flavor was there, but they were a little overcooked and leaned on the rubbery side. Nothing blew me away, but it's still a cool place to hang out, have a drink, and soak in the Keys atmosphere. Sometimes the setting carries just as much weight as the food -- and this place delivers on that. read more

Excellent food and eating spots on the wharf. Favorite lunch spot on the drive down to KeyWest. Loved the stone crab. They serve it cold which I wasn't expecting but it was so flavorful by itself and with the provided sauces. Excellent sweet potato fries and perfect coleslaw that isn't dripping in sauce. Loved the Crab chowder even though it doesn't have as strong of a crab flavor to it Key Lime Pie here might be my favorite of all 9 that we tried on our stay in the Keys. Tart, smooth filling with a sweet crust. Perfection. read more

Initially, I ordered Keys Fisheries food via DoorDash. The fried scallops basket and lobster bisque were meh at best. The hogfish platter was somewhat better, offering a generous portion along with some tasty smashed potatoes. 2 days later, a server at another restaurant highly recommended Keys Fisheries' 2nd floor tiki lounge as the best place in Marathon to partake of a sunset. He was abso-freaking-lutely right! At sunset, the bartender serves up complimentary rum punch shots. There is nothing like a Keys sunset when the last of the sun drops below the horizon like God turning the lights out... The restaurant itself is pretty barebones basic, but I would imagine being next to a marina and commercial fishery, the seafood would be very fresh and perhaps better than a DoorDashed order. I also enjoyed watching a huge swarm of ginormous tarpon and nurse sharks opportunistically awaiting the commercial fish scraps at day's end read more

Keys Fisheries - A magnificent sunset from the upstairs tiki bar - Seafood Markets Near Me - Marathon, Florida

Sometimes basic is better. You order at a window after perusing a huge menu on the wall. Sit at a picnic table overlooking the water. In a few minutes your name is called and go get some of the freshest seafood on the planet. Big portions. Cooked perfectly. You can get pretty much anything here. There's also a full bar with some nice local draft beer choices. The Grouper Ruben was delicious- the normal Ruben ingredients worked great with the grouper. The fish on a bun was fresh and plentiful. If you're looking for a break from the typical (but also good) coastal seafood bar/restaurants this is a place for you. read more

A staff member of the Keys Fisheries could punch me right in the face and I would continue to patronize this establishment because the food here is that freaking good. We are not locals but stay in Marathon once a year and we make darn sure to visit the Keys Fisheries at least once. Our last visit was on 12/27/2025. There were six of us which meant there were six very happy and satisfied people at the end of our experience. Yes, it's true, this is a no-frills restaurant. You walk up to a window and order your food. The menu is on the wall and you can look at it while you wait in line. There will be a line - so what - it moves fast. You give the girl a fake name and then wait for it to be called so you can go back to the window and get your tray of food. Then you find a seat somewhere nearby at a picnic table. Who cares? None of this will matter once you start eating the food. Oh yeah, you can get alcohol here too. Sign me up! I don't remember what I have year after year BUT I will never forget what I had this year - and neither will anyone else! There's a special on the board this time: hogfish francaise or francese however you'd like to spell it. I notice the catch of the day is hogfish. This sounds like a winner. I order it. I get it. I eat it. I am forever changed. I would sell my soul to have this again. Yes - it was that good. I feel bad for my friends and family at this point. I'm not even done half my meal and they already know about this damn hogfish. I've told everyone. I simply can't shut up about how divine this meal was. Could you please stop talking about it? No, I cannot. Hey - I'm coming back in December. Hope you're ready! read more

Nice casual eatery here in Marathon. Right on the water in a marina. You order at the window and in literally no time your order is up. My lovely wife had their Lobster Mac&Cheese and I had the Lobster Bisque with a Lobster Roll. Everything was delicious and large portions. We will be back. Oh yeah don't forget to check out their fish market. Plenty on deals there. read more

The food is really good. Takes a while but worth the wait. The Tarpon and sharks swimming by are very cool. However, blonde girl taking the orders at the counter should not be the face of the company. Can hardly hear her and she speaks in short, barely understandable words and she doesn't interact well with customers. The staff fulfilling orders looked like they were having fun and would be a great front people. read more

We ate here twice because the food was so good and the kids in our group loved seeing the fish, sharks and birds that are around the building. The food was great and the key lime pie is a must. read more

Went here based on Marathon happenings members recommendations. The line was long and not worth the wait. Was hoping we could have dinner and enjoy the view from the upstairs bar but we had our 2 teenage boys. Only 21 and up can go upstairs. We ordered The conch salad had the smallest bits of conch and all greens. Bland The fried seafood platter was disappointing too. skinny fried calamari, fish sticks and shrimp. The conch fritter was over cooked., almost burnt. It might have been a bad day in the kitchen as I was expecting better based on rave reviews. The only positive was the view. read more

Boy was this place fun. We enjoyed the sunset toast a lot. The posts covered with stickers give a festive ambiance. The drinks and food at happy hour were so cheap compared to heat we've been paying. The sashimi was a bit questionable (it had a bit of a fishy quality nobody else cared for but I ate it and was fine), but the crab claws were delicious. Bartender gave me a free soda water for being the DD, thanks, ma'am!! Really enjoyed the festive atmosphere. read more

A great view of a sunset, we came here on a Friday night. We ordered food downstairs at the window and brought it to the upper deck. We ordered 1 Broiled Lobsters with vegetables and rice. At the bar, they had half bottles and we got a half bottle for $14 of the Kendall Jackson Chardonnay. It was neat because at sunset, they hand out "Sunset Shots". Sweet and delicious, it was a cool experience. The Lobster was a tad overcooked but the broccoli was good. Paired with some rice and a little butter, it was decent. Wouldn't say that the service was super friendly but it's a cool experience and a great sunset view. read more

My wife and I have been here before and we're were looking forward to getting lobster rueben sandwiches . It took us at least 30-40 minutes to out in our order and 45 minutes to get our food. People behind us were getting their food before us. The sandwiches weren't as good as our previous experience and the $100 bill was not worth the price experience. Unfortunately, I'll have to say that this is a pass from is on. Not worth the trouble or money. read more

We stumbled upon Keys Fisheries based on a simple Yelp search while on Marathon. We were surprised by the counter service style and picnic tables because food doesn't match. The foot is incredible fresh and elevated. We ordered several things but the stand out to me what the spicy tuna bowl and the ahi tuna nachos. The portion of tuna is unreal. We actually had left over. The flavors were amazing. We watched fish boats come in and got to watch the sunset. It was a great experience. The only bummer was they only use fresh catch and they were out of Lobster. I wanted to try their famous Lobster Rueben. Maybe next time!! read more

Came back to visit a year after my initial visit and my review remains the same. Way more about atmosphere and less about the food. You stand in line to order then wait about 30-45 minutes for your food to arrive (on a slow night-- we actually went on a Monday evening). We fed the tarpon and had some drinks while we waited but the kids started to get hungry and upset. Food was nothing to write home about. The chicken on the sandwich was so thin- the onion pieces are actually bigger than the chicken (see pic). Do not order the chicken sandwich if you are hungry. Key lime pie was as expected. The crab Mac and cheese was the best part. Lots of crab and cheesy Mac. The restroom is located in the parking lot and bit sketchy with only one stall. Parking can get full on a busy night. Parking lot is gravel. The bar is at the back of the restaurant with lots of drink options and quick service. They have seating for 21+ at an upstairs area that generally has live music. read more

Came because of sign saying they had best lobster Reuben but it's not lobster season.. lol oh well they had pretty big menu so hubby tried few things.. grouper Reuben was very good as was the plantains! We had few meals here as the food was good and price was reasonable. The staff was very nice and helpful. The place itself is not fancy it's very laid back.. tables are picnic tables all around the dock on the waterfront.. you can see and feed tarpon but not people food they have feeders you can get food from for 25 cent. There's other fish too that eat the feed so cool experience.. they do sell out of stuff at times so best to get there early.. read more

This place was at the top of my list while visiting Marathon, but it missed the mark. I had one more food stop planned, but after this experience, I'm done until next time. The conch po' boy was extremely overcooked, hard, dry, and unpleasant to eat. The bread was just as tough. The remoulade looked great but did not help. The smashed potatoes tasted like a mix of instant and real, and the texture was off. Two stars only because the seating and view was nice and the staff were very pleasant. The food was a major letdown. read more

Go early to get a lobster roll lol. I got grilled Mahi tacos and lobster chowder. My Wife got shrimp ceviche, it was a small serving but she brought it home for a snack later. She also got the mago shrimp bowl. It was like a sweet and spicy mix but delicious. It was a good saving that she was only able to eat half or it. We got there about 730pm and ther was plenty of seating. Dog friendly as well. A must stop in Marathon. read more

Keys Fisheries checked all the boxes for us! Casual, relaxed atmosphere with delicious fresh food, and a price point that's easy to digest! We would return to this establishment again and again. Tip: the lobster is fresh, so when it's out, the famous lobsters dishes are unavailable for order. Suggest going when they open for lunch if having fresh FL lobster will make or break your experience. read more

This is such a unique fun place to eat at. We certainly added to their count of their lobster Rueben . I highly recommend trying the lobster Reuben that I have to admit. It's my favorite spot for calamari as well. They always have cute names. They have you give them like maybe pick an animal name then they call you by that animal name. The water around them is brooming with tarpon and sharks and funny animal life. We saw a manatee last time we were there as well. This restaurant is always on our list of must do when we come down to the keys. read more

We wanted some good seafood and wanted to be out by the water. Saw this place and it fit the bill. Lots of choices - including the "world famous lobster Reuben" ... which looked interesting but we didn't order it. Instead we all got the fish tacos. They were really good. We had some grilled and some blackened. The ambiance is what you'd expect in marathon. Laid back and relaxing. You order at the counter and they call you when it's ready. Very easy. read more

Keys Fisheries - Mahi tacos - Seafood Markets Near Me - Marathon, Florida

Friday, January 9, 2026.... Outstanding experience. I had a great meal here, sitting by the water. Great food, great service!

This is now one of my favorite places in Marathon, and I'm not easy to please. Yes, you can blow a tremendous amount of money on silly things like a lobster reuben. If that's how you roll, more power to you. However, I think a place really shines with how well it does the simple things: Cold peel and eat shrimp Conch fritters Stone crab claws with mustard sauce Key lime pie The stone crab claws will set you back a pretty penny. But the insider tip is to order them at the upstairs bar where they are cheaper for some mysterious reason. The ambiance is rustic, outdoor, picnic table, marina dining. There's a downstairs bar as well, if you are visiting with minors who aren't allowed upstairs and you want a cold local beer or some kind of fruity cocktail. You want frills? Go someplace else. You want delicious fresh seafood and a delightful (if not the absolute best, a close second) slice of key lime pie, go to Keys Fisheries. Next time I'm in town, it might be hard to get me to eat anyplace else. One last thing. There are dispensers of fish food scattered around the dining area where you can get a small handful of pellets for a quarter. On one visit, the feeding frenzy attracted a couple of curious nurse sharks! So you can get some pretty nifty critter sightings too. read more

This was a MUST-STOP on my list of places to eat. Thank goodness we did because it was so good!! Ordered the must-try lobster Reuben and it did not disappoint! FULL of HUGE lobster pieces, Swiss cheese, sauerkraut, dressing, on toasted rye bread. DELICIOUS! Also had the calamari and fries and also just as delicious! Great fast friendly service. You place your order and seat yourself at the picnic benches. Also got to see the hungry tarpon and nurse sharks in the harbor. Highly recommend to check this place out!! read more

This restaurant is fun because they throw fish scraps to the awaiting tarpon and nurse sharks. It's quite a show. There was also a manatee cow and her calf swimming by when we came. The food wasn't very impressive, we had conch fingers which were very greasy and my mahi tacos were pretty bland. We also had a slice of key lime pie which was good. There is no service here because you order from a window. There's nothing particularly wrong with this restaurant but other than the shark show I really would have no reason to come back. read more

Right on the water, fresh seafood. Had the Mahi fish tacos, delicious. The cole slaw not so much, should have gotten the fries.

The service started off on weak footing when as I was talking to my wife, and the server shouts to me "I can't hear you". She apparently thought I was talking to her when I was having a conversation with my wife. I played it off. We ordered a bunch of food and was really disappointed to see the conk ceviche come in a pre wrapped sealed plastic container like you'd get from Costco. This is supposed to be the fish market that delivers to all the other local "fish markets". We accidentally dropped it on the floor and the staff was very nice about it and replaced it. The conch fritters were mostly air and breading. I didn't taste much conch. The seafood mixed grill was ok. 7/10. The entire bill with no cocktails was $90. I left there feeling like a sucker. But good news. They charge you $17 a pound to cook any fish that you catch. Robbery. read more
