The building at 4910 Main Street has been three different restaurants in the past several years. It opened as Mac's Grill, became Pig N' Pit, and this past March reopened again as Tower 31, a breakfast-to-dinner spot from Nathan Smith, who moved his family to Spring Hill from California five years ago. The name is a small joke about the move: Tower for the lifeguard towers on Southern California beaches, 31 for the highway that runs past the front door. There's even a menu for dogs.
Three concepts in one storefront in a handful of years is the kind of detail that looks like noise until you notice where it's happening. It isn't scattered across town. It's on a specific stretch of Main Street, roughly the two-thirds of a mile between Kedron Parkway and Miles Johnson Parkway, and that same stretch has absorbed nearly every piece of restaurant news Spring Hill has produced this year. Understand why that particular run of road keeps changing hands, and you understand something about where this town's center of gravity is actually settling, not the version a generic visitor guide would tell you.
The Half-Mile, Mapped
Line up what's opened or is trying to open along that corridor in the past twelve months and the pattern is hard to miss:
- Tower 31, 4910 Main Street, opened March 2026 in the former Mac's Grill and Pig N' Pit space
- Pita Way, 4816 Main Street, opened late 2025 as only the chain's second Tennessee location after Franklin
- Aubrey's, proposed at Main Street and Miles Johnson Parkway, still working its way through Spring Hill's planning process years after it first came before the Planning Commission, for what would be the East Tennessee chain's first restaurant in Middle Tennessee
Two of those are already serving food. The third is still on paper, and that's the more interesting detail. Aubrey's runs 14 locations across East Tennessee and has never crossed into Middle Tennessee before. The company has been willing to sit through a permitting process that has stretched on for years for this specific corner of Main Street rather than build somewhere with a faster path to opening. A regional brand doesn't wait that long for a location unless the location is worth waiting for.
Where The Drive-Thrus Go Instead
Not every chain is fighting for frontage on Main Street, and the ones that aren't tell you something too. In 2025, Whataburger made a second attempt at a Spring Hill location, this time eyeing the old KFC building at 3004 Belshire Village Drive, a block off Main near the Highway 31 intersection. The chain had site plan approval back in 2022 for the old Burger King location nearby but never built. The 2025 proposal called for minimal changes to the existing building, plus a new pedestrian sidewalk and crosswalk along Belshire Way.
That's a different kind of real estate calculation than the one Aubrey's is making. A quick-service brand wants visibility from the highway and an easy drive-thru lane, not a walkable storefront on the strip everyone already treats as downtown. So Spring Hill is quietly sorting itself into two types of commercial ground: sit-down, from-scratch concepts fighting for the actual Main Street corridor, and drive-thru brands filling in the arterial a block over. If you've wondered why the fast food chains never seem to land on Main itself, that's the reason. They aren't trying to.
The Second Pole Forming At Port Royal And Duplex
The other project worth watching sits well outside that corridor entirely. Sprouts Farmers Market has been confirmed as the anchor tenant for a new development called Port Royal Marketplace, at the intersection of Port Royal Road and Duplex Road. The store is planned at roughly 23,000 square feet, construction is expected to start sometime in 2026, and an opening is projected for 2027.
A national grocer choosing that intersection over a spot in Franklin or Brentwood is a retail decision, not a lifestyle one, and retail decisions like that tend to pull other tenants along with them. Grocery anchors don't get placed on guesswork. Sprouts picked Port Royal and Duplex because the population density and drive-time math already work, which means the corner is likely to fill in with smaller retail and restaurant space once the anchor is under roof. For now it's a construction site, not a destination, but it's the second pole this town is building around, separate from the Main Street corridor that's already active.
What's Already Filling In Around It
None of this is happening in a vacuum. Main Street already carries a weekly rhythm that existed before any of the new storefronts opened, and it's worth knowing if you're timing a visit or just trying to figure out where everyone actually goes.
| Day | Where | What |
|---|---|---|
| Saturday | Hidden Gem Farmers Market, 863 Old Military Road | Runs every Saturday through October, 11 a.m. to 2 p.m. |
| Monday | Grecian Family Restaurant and Bakery | BrainBlast Trivia |
| Tuesday | Grecian Family Restaurant and Bakery | BrainBlast Bingo |
| Wednesday | Grecian Family Restaurant and Bakery | Kids eat free with an adult entree |
| Monthly, spring through fall | Harvey Park, Red Oak Pavilion | Pickin' in the Park, an outdoor acoustic music series now in its second decade, with a recent 2026 date on August 22 |
None of that is dramatic on its own. What's notable is how much of it clusters within a few minutes of the same stretch of Main. A farmers market on Saturday, trivia and bingo on weeknights, a monthly concert at the park, and now three sit-down restaurants that didn't exist a year ago, all inside the same half-mile. That's not a coincidence of geography. It's what happens when a corridor starts functioning as a town center even though nobody built it that way on purpose.
The One Weekend That's Been Anchoring October For Twenty Years
Step outside the corridor for the one event that pulls the whole town together, and it lands in October at Oaklawn Mansion on Denning Lane. What started in 2005 as the Country Ham Festival has been rebranded as the John Maher Builders' Whole Hog Festival, and it's grown into Spring Hill's largest annual gathering, benefiting The Well Outreach, the local food pantry serving families in Spring Hill and Mount Pleasant. The organization's own event page confirms this year's date as October 17, marking the festival's 21st year.
The October timing isn't an accident. In 2006, organizers worked with the state legislature to have the first Saturday in October declared Tennessee's official Country Ham Day, and the event has anchored to fall ever since, even after the rebrand traded ham curing demonstrations for a whole hog, live music, a hog-calling contest, and a kids' zone. Recent editions of the festival have drawn upward of 7,000 people, a number that says less about the food and more about how few other events in Spring Hill pull that kind of crowd to one place.
What This Actually Means If You Live Here
None of this is a reason to do anything differently tomorrow. But it does answer a question a lot of residents have probably asked without quite putting words to it: why does it feel like everything new keeps happening on the same stretch of road, and why doesn't Spring Hill have an old town square the way Franklin does. The answer is that it's building one now, in real time, on Main Street between Kedron and Miles Johnson, with a second cluster starting to take shape a few miles away at Port Royal and Duplex once Sprouts breaks ground.
