Thirty years ago, a golf instruction company called Golftec signed its very first retail lease on the northeast corner of Belleview Avenue and Ulster Street. The company grew from that single storefront into a chain with more than 250 locations worldwide, eventually outgrowing the space and moving about a mile north. This year, Golftec is coming back. It has leased 3,300 square feet in the same spot where it started, now rebuilt from the ground up and rebranded as On The Square.
That homecoming is a small detail in a much bigger story. But it says something true about how this corner of Denver Tech Center works: things that leave tend to come back different, and the people filling in the gaps right now are being unusually deliberate about not repeating what's already there.
The corner got a $200 million reset
The site was once known as Marina Square, a 13-acre retail center that had been sitting underused for years. Shea Properties bought into a full teardown-and-rebuild after a lengthy rezoning process, breaking ground last summer on what is now a roughly $200 million redevelopment. The core and shell work delivered in early August 2026, with tenants expected to open in stages from later this year into early 2027.
That timeline matters if you live nearby and have been watching the fencing go up without much else to show for it. The building shells exist now. The businesses moving into them are what will actually change your Tuesday night.
What one restaurateur said no to, three times
The most telling quote in any of the reporting on this project doesn't come from Shea Properties. It comes from Sean Huggard, the founder of Shucking Good Hospitality, who already runs two restaurants a short drive from this corner: Blue Island Oyster Bar & Seafood and Oliver's Italian, both in nearby Greenwood Village.
When asked what his new concept for On The Square would be, Huggard answered mostly in the negative. It would not be a steakhouse. It would not be another Oliver's, because that already exists down the street. And it would not be another Blue Island either, since the new site sits roughly equidistant between his existing Blue Island locations in Cherry Creek and Lone Tree.
What he landed on instead is The Coastal Service, a raw bar and seafood concept built around his years cooking on Nantucket rather than around the Long Island oyster farm that anchors Blue Island. Same East Coast lineage, different menu, different reason to exist.
That's the part worth sitting with. A restaurateur with two successful concepts already operating minutes away is choosing to build something distinct rather than a third version of what's working. That only makes sense if the surrounding dining pool has gotten dense enough that duplication would actually cannibalize his own business. Read that way, Huggard's list of what he's not building is a quiet admission that this stretch of DTC has crossed some threshold of restaurant density it didn't have a few years ago.
The rest of the roster reads like a deliberate mix, not a grab bag
The Coastal Service isn't opening alone. On The Square's confirmed tenant list mixes formats in a way that looks intentional once you line it up:
| Business | Type | Local detail |
|---|---|---|
| The Coastal Service | Seafood and raw bar | New concept from Shucking Good Hospitality, opening early 2027 |
| Barcelona Wine Bar | Spanish tapas | Second Denver-area location, bringing about 80 jobs |
| Sweetgreen | Fast-casual salads | Its eighth metro Denver location |
| Mendocino Farms | Fast-casual sandwiches | Its fourth metro Denver location |
| Solidcore | Fitness studio | Pilates-based strength training |
| Golftec | Golf instruction | Returning to its original 1995 storefront site |
Notice the pattern. Two full-service, sit-down restaurants with real wine and cocktail programs, paired with two fast-casual chains built for a lunch crowd, plus a fitness studio and a golf instruction company. That's a tenant mix built for both ends of a workday: quick weekday lunches for the office towers that made Denver Tech Center an edge city in the first place, and a reason to stick around after 5 p.m. for dinner and a glass of wine instead of driving somewhere else.
Barcelona Wine Bar's arrival is worth a second look on its own. The chain has operated a Five Points location on Larimer Street since 2018 and, according to reporting from the Denver Business Journal, its CEO said the company wasn't actively hunting for a second Denver location until the Belleview and Ulster site came up. Something about the corner changed his mind.
The evening crowd was already forming before any of this broke ground
None of this restaurant activity is filling a vacuum. A few blocks from On The Square, the Crescent Amphitheater at DTC Boulevard and Belleview Avenue just wrapped its 2026 season of Concerts at the Crescent, a free Tuesday evening series that ran from June through the first week of August. This was the series's 30th year, meaning residents in this corridor have had three decades of practice showing up on a weeknight with a lawn chair and a picnic dinner for a free show a short walk from home.
That's a long-running habit that predates every restaurant on this list. It means the audience Huggard and Barcelona Wine Bar are betting on isn't hypothetical. It's a corridor of people who already treat a Tuesday night near DTC Boulevard and Belleview as worth getting dressed for, even without dinner reservations attached to it.
What this actually changes if you already live here
If you've been driving past a fenced construction site at Belleview and Ulster for the better part of a year wondering what was coming, the honest answer is: not a strip mall replacement, and not a copy-paste of what's a mile away in Greenwood Village. The tenant list reads like an attempt to give this specific corner its own identity, distinct from the Blue Island and Oliver's crowd nearby, distinct from the chain-heavy retail that used to define this stretch of DTC.
The near-term reality is patience. Core and shell construction finished in early August 2026, but Shea Properties has said the actual tenant openings will stagger from later this year into early 2027, so don't expect all six of these businesses to open on the same weekend. Golftec and the fast-casual chains are likely to move faster than the two full-service restaurants, which take longer to build out kitchens and dining rooms.
What's clear already is that the corner isn't just being rebuilt. It's being rebuilt with an eye toward not repeating itself, and toward giving people who already live and work near DTC Boulevard a reason to stay put on a weeknight instead of driving into Cherry Creek or Lone Tree for the same experience.
If you're watching this corridor evolve and any of it eventually turns into a real estate conversation, whether that's a listing, a purchase, or just understanding how a neighborhood's amenity base is shifting, First Alliance Title has been closing transactions across the Denver Tech Center and greater Denver-Boulder metro for years, with a local team that pays attention to exactly this kind of change on the ground.
