On the night of January 21, 2026, a crowd gathered outside a storefront at 11399 Overseas Highway in Marathon Shores, waiting for a ribbon to be cut in front of a sign that read Lalo's in cursive neon. Eduardo Sanchez stood near the door with his wife, Yarima Yera, and his head chef, Giovanni Cardona, greeting people who already knew his face. For a decade, Sanchez had run the floor at Lazy Days South on the other end of town. Everyone in that crowd had eaten his food before. They just hadn't eaten it here.
That detail matters more than it looks like it should. Marathon's food scene has had a run of attention over the past year and a half, and if you've scrolled past a listicle or two, you already know the names: a sushi spot with wooden boat trays, a resort restaurant with a new chef, a market that reopened after sitting dark for years. What those roundups tend to miss is the thread connecting them. None of these are new businesses built from scratch by outside money. They're second acts, run by people who already had a foothold here, reoccupying buildings and reputations that needed rebuilding rather than inventing something from nothing. If you live in Marathon, that's the part worth understanding, because it tells you something about how this town's dining scene actually renews itself.
A Sushi Bar Built on a Decade of Regulars
Lalo's had technically been open for a few months before that January ribbon-cutting, quietly finding its rhythm before the formal celebration. The name itself has a backstory: at his previous job, Sanchez was one of three men who shared the same first name, so coworkers started calling him "Lalo" to keep shifts straight. A decade later, that nickname is the restaurant's identity.
The kitchen's signature move is presentation. Cardona serves rolls on traditional wooden sushi boats, decorates plates with orchids, hibiscus and frangipani, and treats every dish, in his words, like a canvas.
"When a guest sees a boat approaching their table, their eyes light up before they even take the first bite," Cardona said at the opening. "We believe that you eat with your eyes first."
The menu extends well past sushi, with cooked options meant to cover a table of mixed appetites, and the happy hour built around $7 and $8 specials has become a draw for people winding down after a day on the water. Lalo's is open daily for lunch and dinner. What you're getting, more than a new concept, is an operator who already had ten years of trust built up in this town and finally opened his own door.
The Rhum House Gets a New Chef and a New Chapter
A few miles up the highway on Grassy Key, the Rhum House has been going through its own reinvention. The restaurant sits inside Grassy Flats Resort, the property built by Matt Sexton, a former professional kiteboarder and wakeboarder who also owns the Lagoon on Grassy Key wakeboard park, Keys Cable Park and Bongo's. Sexton's original plan for the Rhum House was straightforward: food to keep guests at the adventure park longer. It became something bigger, and late last year it entered what Sexton calls a new chapter, with a rebuilt space, a revamped menu, and a new executive chef, John DeLoach.
DeLoach's stated goal is to make fresh Keys ingredients accessible without turning the room into a white-tablecloth experience. Sexton has been explicit that he wants to avoid that trap entirely.
"I'm a foodie and I love to experience different cuisines, have fun, enjoy some craft cocktails, share some apps and not break the bank every time I go out," Sexton said. "That's the goal with the Rhum House."
The upstairs companion space, the Palm Deck rooftop bar, runs its own menu and its own happy hour, and the sunset views from up there have become a reliable draw on their own. If you've been meaning to check it out, plan around the calendar: the Rhum House is closed from September 8 through October 9, 2026, part of its regular seasonal downtime. The Palm Deck's hours shift separately, so it's worth checking before you drive out expecting both to be open.
The Building That Sat Empty for Seven Years
The most telling story in this whole stretch of highway isn't a restaurant at all. It's a market.
The storefront at 58152 Overseas Highway has a long memory for anyone who's lived in Marathon a while. It was the Dairy Bar, then it became Grassy Key Outpost, and then Hurricane Irma hit and the building sat shuttered for seven years. Sexton had his eye on the space that whole time, even while he was building out Grassy Flats and the Rhum House right behind it. In early 2025, it reopened as the Grassy Key Land and Sea Market, a butcher shop, fish house, bakery, deli and grocer under one roof, plus a coffee program called Grassy Grinds.
The market's meat counter is run by Mike Shaner, a third-generation butcher whose family operated Shaner Land and Sea Market on Pass-a-Grille Beach. Sexton had talked for years about wanting to open a Keys version of that shop if the family ever sold, and when Shaner became available, he moved down to run it.
"I'm very transparent with our customers," Sexton said of the market's approach. "I'm able to tell them that this fish was caught in the Florida Keys, where it was caught, the name of the guy who caught it, and sell that out of our market today or sell it out of one of our restaurants tonight."
The market also inherited the Rhum House's pastry chef, Hailey Pacyna, who moved her operation down the road to bake for both locations. It's open daily from 6 a.m. to 7 p.m., which makes it as much a coffee-and-pastry stop before a fishing trip as it is a place to pick up dinner ingredients.
What the Pattern Actually Tells You
Put those three stories side by side and the shape becomes obvious. Lalo's is a longtime staff member finally getting his own restaurant. The Rhum House is an existing property investing in a new chef rather than starting over somewhere else. The Land and Sea Market is a building that had been empty since 2017 getting a second life because one operator refused to give up on it. None of this is a chain moving in or an outside developer testing the market. It's the same small group of local owners, several of them connected to each other through Sexton's businesses, recirculating buildings and talent that were already here.
That matters if you're trying to read what's actually happening to Marathon's food scene, as opposed to what a generic "best new restaurants" post will tell you. The town isn't getting flooded with outside investment. It's getting reinvestment from people who already had equity, literal and reputational, in this stretch of the Keys. Grassy Key in particular has gone from having one well-known kitchen to functioning almost like a small food district, all built by the same hands.
It's also worth remembering that some of Marathon's dining reputation was already solid before any of this happened. Lighthouse Kitchen + Bar, with its water views under the town's historic lighthouse, had its pet-friendly patio voted a TripAdvisor Best of the Best pick for 2025 and ranked among the top five pet-friendly dining spots in the entire country. The new openings aren't replacing that kind of established favorite. They're filling in around it, which is a healthier sign for a food scene than any single flashy opening would be on its own.
A Quick Reference If You're Planning a Night Out
- Lalo's Bar & Restaurant – 11399 Overseas Highway, Marathon Shores. Open daily for lunch and dinner, with a happy hour built around sushi boats and specialty rolls.
- The Rhum House – Grassy Flats Resort, 58182 Overseas Highway, Grassy Key. Closed September 8 through October 9, 2026 for its seasonal break. The Palm Deck rooftop bar keeps its own separate hours.
- Grassy Key Land and Sea Market – 58152 Overseas Highway, Grassy Key. Open daily from 6 a.m. to 7 p.m. for butcher counter, bakery, coffee and grocery items.
None of these are secrets anymore, and they weren't built to be. But knowing the story behind them, who used to work where, what building sat empty and why, is the difference between eating well in Marathon and actually understanding the place you live.
If Marathon's evolving food scene has you thinking more broadly about what's changing in this stretch of the Keys, from new businesses to the property around them, that's exactly the kind of local read The Cascone Team tracks closely. Let's Connect.
