Third Street's New Restaurants Aren't Anyone's First Try

Walk Third Street in Jacksonville Beach this month and you'll pass two addresses that used to be something else. At 1700 Third St, Grouper Shack now occupies the space that spent years as The Bearded Pig, the barbecue spot that closed in April 2025. A few blocks north at 311 Third St N, Bella Vista A'Mare has taken over what was Biggies Pizza, the space next door to Rita's. Both storefronts sat empty for a stretch. Both reopened within about two months of each other. Neither reopened as someone's first restaurant.

That last detail is the part worth sitting with if you already live here and have watched this stretch of Third Street cycle through tenants for years. The easy read is "new energy on Third Street." The more accurate read, once you look at who's actually behind these two openings, is that Third Street's turnover isn't being absorbed by first-time restaurateurs betting everything on one shot. It's being absorbed by operators who already have a working formula somewhere else and are testing whether it travels to the beach.

Two Doors, Same Block

Grouper Shack opened December 20, 2025, in the former Bearded Pig space, run by Nathan Stuart and his wife Margo Klar, who describe the build-out, including a retail Marketplace selling portioned fish and oysters to prepare at home, at roughly a million dollars. The restaurant launched with a fifty-person staff and called its first month a training and soft-opening period. This is not Stuart and Klar's first Grouper Shack. They already operate one in St. Augustine, along with several other Northeast Florida restaurants, including The Fish House & Oyster Co.

Bella Vista A'Mare followed into the old Biggies Pizza spot, bringing chef Giovanni Prignano's coastal Italian menu, Cacio e Pepe, Veal Milanese, Pistachio Martinis, along with murals of the Amalfi Coast, to a room that seats around 125. Prignano and his wife Alysha run it together, the same way they run the original Bella Vista in Fruit Cove, where the concept first proved itself.

Both businesses are expansions, not debuts. Both owners had already worked out their kitchen, their staffing model, and their pricing somewhere else before bringing it to this specific block.

The Pattern Underneath the Turnover

If you've lived near Third Street long enough to remember three or four restaurants cycling through the same footprint, this pattern explains something the "new restaurant alert" version of this story misses. A corridor that turns over restaurants regularly isn't automatically a struggling one. It can also be a corridor where the rent, the foot traffic, and the seasonal swings favor operators who've already absorbed the risk of a concept somewhere else, rather than someone testing an idea for the first time with their own savings on the line.

That's a meaningful distinction for a resident. A block full of first-time restaurants is a block still finding its identity, prone to abrupt closures while owners learn on the fly. A block that resets vacant spaces with proven multi-unit concepts is a block that's already been vetted by someone else's balance sheet. Grouper Shack didn't have to guess whether its seafood-market concept worked. It had St. Augustine's answer already. Bella Vista A'Mare didn't have to guess whether Prignano's menu would find diners. Fruit Cove already told them.

What Doesn't Turn Over

The other half of the story is the restaurant that hasn't needed replacing. SoNapa Grille, further along Third Street, isn't new and isn't reinventing itself. It just updates its seasonal offerings, and this month's rotation includes a pistachio-crusted snapper served over mashed potatoes with a citrus beurre blanc, a pineapple upside-down cake with candied pecans and bourbon caramel, and a couple of new cocktails built around elderflower liqueur.

That's the quieter form of change on this corridor. Instead of a new sign and a new build-out, it's a kitchen adjusting four or five items twice a year and keeping the same address it's had for a while. If Grouper Shack and Bella Vista A'Mare are the corridor absorbing turnover through proven expansion concepts, SoNapa Grille is the corridor's evidence that staying put and refreshing incrementally is the other viable path. Third Street currently has room for both strategies, which says something useful about how forgiving the block is right now for restaurants that get their model right the first time, wherever "the first time" happened.

The Same Corridor, Three Blocks Wide, This Saturday

None of this happens in isolation from the rest of the city's calendar, and this particular Saturday is a useful example of how much is stacked into a small footprint here. On August 22, the city's own events calendar lists three separate happenings within blocks of each other: the Hammerhead Ocean Marathon runs on the beach in front of the Lifeguard Station from 8 a.m. to noon, the Veterans Legacy Community Festival runs at Latham Plaza and Seawalk Pavilion from 9 a.m. to 7 p.m., and the Beaches Green Market sets up at Penman Park from 10 a.m. to 2 p.m. Three different crowds, three different reasons to be outside, all inside a few minutes' drive of each other.

A few days later, on August 25, the Jax Beach Classic Car Cruise takes over Seawalk Pavilion and Latham Plaza from 4 to 7 p.m. If you'd rather stay closer to the water on any given weekend, LandShark Bar & Grill runs live music Friday and Saturday from 5 to 9 p.m. and Sunday from 4 to 7 p.m., rain or shine on the schedule if not on the weather. The Beaches Museum has its own quieter calendar running in parallel, with a Right Whale closing reception and film screening on August 25 and Beaches Book Day on August 29.

None of these events depend on each other, and none of them are really about the restaurants on Third Street. But they're happening in the same compressed geography, which is part of what makes this stretch of Jacksonville Beach function the way it does. A resident deciding where to eat before or after the car cruise, or between market stops, is choosing from a corridor where at least two of the newer options arrived with someone else's track record already behind them.

Reading Third Street Like a Local

The honest version of "what's new in Jacksonville Beach" isn't just an inventory of what changed. It's a read on why those particular changes happened and what they tell you about the block you already know. Two restaurants took over two closed spaces on Third Street within two months of each other, and neither one is a first attempt. That's not a coincidence worth ignoring if you're the kind of resident who notices which storefronts get filled quickly and which ones sit empty for a year. It suggests the operators willing to take a chance on this stretch right now are the ones who've already proven the concept somewhere else first.

If you've lived here long enough to remember what used to be at 1700 Third St or what Biggies Pizza's dining room looked like before the murals went up, you already have the kind of neighborhood memory that makes a change like this legible instead of just noticeable. That's also the same instinct that matters when the conversation eventually turns from where to eat dinner to what a home on this same stretch is actually worth. When that day comes, Julie Little Brewer has spent more than three decades reading this exact corridor, from its restaurant turnover to its property values, and is always glad to talk through what she's seeing, no obligation attached.
