For a long stretch of years, if you lived on Key Heights Drive and wanted a real dinner out, the working assumption was simple: drive south. The building at Mile Marker 88 sat behind construction fencing for so long that it stopped registering as a restaurant and started registering as scenery. The old resort a few miles down felt tired, the kind of place you drove past rather than into. Key Heights, sitting almost exactly between the two, felt like a residential pocket with nothing much on either side of it.
That assumption no longer holds, and it stopped holding almost without anyone noticing.
The bookend that reopened
Marker 88 has been a Plantation Key fixture since 1967, but for a stretch of years it existed mostly as a memory and a fenced lot. The restaurant reopened on June 1, 2023, after a multi-year renovation that expanded the property to 2.5 acres, added a second tiki bar, put 18 craft beers on tap, and built out 10,000 square feet of beach and oceanfront dining. Two boat docks mean it works for the neighbor who drives over on Overseas Highway and the neighbor who ties up instead. The current hours run 11 a.m. to 9 p.m. Monday through Thursday, later on Friday and Saturday, with Sunday brunch service starting at 10:30. It sits at 88000 Overseas Highway, which puts it at the northern edge of what most people consider Key Heights territory.
The renovation is the part locals lived through. The reopening is the part that changed the math on where dinner happens.
The one that wasn't there before at all
A few miles north, near the entrance to Islamorada off Tavernier Creek, Lido 73 opened in the fall of 2024. This one is not a reopening. Tony and Isis Wright, who already run Italian Food Company nearby, built it from scratch at 90451 Old Highway, in a quiet basin that used to house a dive center. They kept a piece of that history: the indoor seating displays underwater photography from Stephen Frink, whose work has documented Florida Keys reef life for decades. Outside, there is 300 feet of dockage, so arriving by boat is as normal as arriving by car or golf cart.
The menu leans coastal Italian, heavy on seafood and wood-fired flatbreads, and the restaurant runs live music on Thursday and Friday nights. It is open early, from 7:30 in the morning most days, which makes it as much a breakfast option as a dinner one. For anyone on the Key Heights side of the bridge, this is now the closer option heading toward Key Largo, not the farther one.
The one hiding inside a rebranded resort
Head the other direction, south past Founders Park, and the old Postcard Inn is gone in name and mostly gone in spirit. It is now Three Waters Resort, and inside it sits Kindler Wood-Fired Fare at 84001 Overseas Highway. Kindler runs an open kitchen built around live-fire cooking, dry-aged meats, and a daily seafood selection, with a bring-your-catch option where the kitchen will build a dish around whatever came off your line that afternoon.
Here is the detail that actually matters if you live here rather than visit here: Monroe County residents get 15 percent off the check with local ID. That is not a promotion aimed at the tourist filling a hotel room upstairs. It is a standing discount aimed at the person driving down from Key Heights on a Tuesday night. Happy hour runs Wednesday through Sunday from 5 to 6 p.m., and the restaurant has hosted an annual multi-course wine dinner called Helm to Hearth each April, now in its third year, pairing James Beard and Michelin-recognized chefs with a benefit for the Coral Restoration Foundation.
The 15 percent Monroe County discount at Kindler is not a tourist perk. It is written for the person with a Florida driver's license, which means it is written for Key Heights.
Why the six miles matters more than any single restaurant
Draw a line from Lido 73 near Tavernier Creek down to Kindler at Three Waters, and you get roughly six miles of Overseas Highway. Key Heights sits inside that stretch, with Marker 88 practically at its front door and Lido 73 just up the road toward Tavernier. Three years ago, two of those three anchors did not function as restaurants at all. One was fenced off. One was a resort restaurant nobody talked about. The third did not exist.
What changed is not that Islamorada got a new restaurant. Islamorada gets new restaurants regularly. What changed is that the immediate radius around Key Heights, the part of the drive most residents treated as connective tissue between the neighborhood and wherever dinner actually happened, is now the destination itself. The reshuffle happened in less than three years, which is fast enough that plenty of longtime residents are still operating on the old map.
The practical version, for a Tuesday night decision
A few things worth keeping straight if you are deciding where to go tonight rather than reading about the concept of it:
- Marker 88 is the closest by far if you are coming from Key Heights Drive itself, and it is the one with dock access if you are arriving by boat rather than car.
- Lido 73 opens earlier than either of the others, which makes it the practical breakfast or brunch stop, not just a dinner option.
- Kindler is the one to bring a Monroe County ID to, since the 15 percent discount only applies with local proof of residency, and the Wednesday through Sunday happy hour window is worth building a plan around if you want the wood-fired menu without the full dinner price.
- If you are hosting out-of-town guests, Lido 73's dockage and Marker 88's two docks both solve the problem of where to park a boat while everyone eats.
None of this requires a special occasion. That is the actual shift. A year ago, all three of these choices required either patience for a renovation, a drive past a resort nobody recommended, or a restaurant that had not opened its doors yet. Now they are just Tuesday options, sitting inside a stretch of highway that used to be the part of the drive nobody thought about.
What this says about the neighborhood, not just the food
None of this is really about restaurants. It is about how quickly a neighborhood's daily geography can shift without a single new house getting built. Key Heights did not change. The buildings around it did, and in doing so they redrew the boundary of what counts as local. The instinct to drive south for a real dinner was accurate for years and is now outdated by roughly three restaurant openings and one resort rebrand.
That kind of shift tends to happen quietly in a place like this. Plantation Key does not run press releases when a restaurant reopens or a resort changes hands. The people who notice first are the ones already living close enough to walk in, or close enough to notice the fence finally came down.
If you already live in Key Heights, none of this changes anything about your address. It changes what that address is fifteen minutes from.
If you are watching this stretch of the Upper Keys from further away, curious about what life actually looks like inside a neighborhood you have only seen through listing photos, this is the kind of texture that does not show up in a spec sheet. The Florida Keys Sold Sisters spend their days on this exact stretch of highway, between the same mile markers, and know which dock to tie up at before dinner. If Key Heights or the surrounding Upper Keys waterfront has caught your attention, start your island home search and schedule a personal consultation whenever you are ready to talk specifics.
