Around 300 people crowded into Main Street on September 14 to watch a red ribbon get cut in front of a building that had been dark since 2015. According to TAPinto Flemington/Raritan, businessman Neal Hart built the original Union Hotel in 1814 as a stagecoach stop. Local developer Jack Cust got borough approval to redevelop it in 2020, and the hotel opened to guests on September 15, 2026.
Four weeks in, the hotel at 74 Main St. is only partly finished in the ways that matter to someone who lives here. Two of its three food and drink venues are serving. The third, the one with the bowling lanes, still has no opening date. The valet setup at the curb out front is a 60-day police pilot that expires around mid-November. Flemington's busiest downtown nights of the season, from the Halloween parade to the Hunterdon Holiday Parade on December 5, fall right across that stretch.
Two Rooms Are Open and One Is Still Dark
The hotel is run by Concord Hospitality Enterprises Co. as part of Marriott's Tribute Portfolio. The project also includes 20,000 square feet of retail and conference space. Sources disagree on the room count. TAPinto's reopening story says 105 rooms. Its July coverage said 100. For a local, the room count matters less than what's on the ground floor and the second floor.
| Venue | Status as of Oct. 11, 2026 | What it is |
|---|---|---|
| Jersey Prime Steakhouse | Open for breakfast and dinner | House-aged steaks, house-made pasta, seafood, raw bar, cocktails |
| Jersey Prime Steakhouse Bar | Open evenings | Cocktails, beer, wine, bar food; smart-casual dress code |
| JP's Lounge | Open Tuesday through Sunday evenings | Second-floor cocktail bar with a terrace |
| Fieldhouse Social | Not yet open; no date announced | Sports bar with duckpin bowling, golf simulators, darts, shuffleboard |
NJ.com's September 3 report described Jersey Prime's menu as steaks dry-aged in-house, house-made pasta, seafood and a raw bar. The restaurant's own site describes an Italian influence and lists brunch along with dinner. The Hunterdon County Chamber of Commerce was founded in 1916 in the same building that now houses the steakhouse, according to Chris Phelan, the Chamber's president.
The second-floor bar has gone by three names in two months. NJ.com called it JP's Cocktail Parlour. TAPinto called it JP's Speakeasy. Marriott's current dining page lists it as JP's Lounge, which is the name to search for now. It's closed Mondays.
Fieldhouse Social is the venue built for a weeknight with kids or a group of friends. It's also the one that's late. TAPinto's July report said it was scheduled for the fall. WRNJ's September 16 coverage still said later in 2026, with no exact date. The hotel itself slipped once already. Its original July 15 opening was postponed on July 20 to a date the statement left open, so a target date isn't the same as a confirmed one.
The Hours Depend on Whose Page You Check
That trial-period feel shows up in the hours too. The two official sources don't agree.
- Marriott's dining page: Jersey Prime serves breakfast daily from 6:30 to 10:30 a.m. and dinner from 4 to 9 p.m. Sunday through Thursday, and 4 to 10 p.m. Friday and Saturday. The steakhouse bar runs 4 to 11 p.m. Monday through Saturday and 4 to 10 p.m. Sunday.
- JP's Lounge on the same page: 5 to 11 p.m. Tuesday through Thursday, 5 p.m. to midnight Friday and Saturday, 5 to 10 p.m. Sunday.
- Jersey Prime's reservation page: dinner until 10 p.m. Monday through Thursday, 11 p.m. Friday and Saturday, and 10 p.m. Sunday. A separate note on the same page says the weekday kitchen closes at 9.
The restaurant takes bookings online through OpenTable from its reservations page. Neither source says reservations are required or spells out a walk-in policy. For a late Thursday dinner, the 9 p.m. kitchen close is the safer number to plan around until the two pages match.
The Curb Out Front Is on a 60-Day Trial
Parking around the hotel was settled long before opening day, and that history explains the current arrangement. According to TAPinto's October 6 report, the borough council passed a series of ordinances in 2025. They set up a residential permit parking system, created a traffic flow pattern around the hotel complex, and banned trucks from certain residential streets.
On Main Street itself, three different arrangements now sit side by side. The planning board approved two spaces in front of the hotel for deliveries and drop-offs as part of the final site plan. At the September 14 council meeting, an ordinance that would have given one more Main Street space to valet parking was introduced and then tabled. Mayor Marcia Karrow said the council had instead authorized Police Chief Jerry Rotella to use his emergency powers to allow valet parking for 60 days to study the impact. TAPinto reported that the police have marked three spaces for that pilot. The mayor described its purpose this way:
"The three that are currently marked by the police department for valet is under a pilot program to try to prevent a backup on Main Street to see if it's really necessary."
She added that any permanent allocation would come through a license the council grants and reviews every year. Sixty days from a September 14 authorization runs out around mid-November. Whatever the borough decides about those three spaces should come up at a council meeting before the holiday season starts.
For anyone driving in for dinner, the hotel's overview page lists self-parking at $15 a day. Valet is $15 for up to 12 hours or $20 overnight, subject to availability. TAPinto has found no published count of how the hotel has changed public parking availability since it opened. No measurement of its effect on other Main Street businesses has been reported either.
Main Street's Busiest Nights Land Inside the Trial
The hotel's first holiday season overlaps with downtown's most crowded dates. It also overlaps with the borough's own street closures. Here's the calendar from the Love Flemington event listings and the borough:
- Sunday, October 18, 3 to 8 p.m.: Phoenix Rising, a free arts, wellness and breast cancer awareness event at Mia Art on Mine, 30 Mine St.
- Thursday, October 29, 5:30 to 7:30 p.m.: The Kids Halloween Parade & Costume Contest at Court Street Park, 71 Main St., with music, trick-or-treating, a costume contest and a photo booth.
- Friday, October 30, 6 to 10 p.m.: The Stangl Witch Walk & Moon Market on Stangl Road, with a Haunted Carnival theme, vendors, food, music and a costume contest. You must be 21 or older to buy alcoholic drinks.
- Saturday, October 31, 4 to 8 p.m.: Borough trick-or-treating. From 5 to 8 p.m., Broad Street is closed between William Street and Pennsylvania Avenue, and Bonnell Street is closed at Park Avenue and Shields Avenue.
- Thursday, November 26, 9:30 to 11 a.m.: The Annual Turkey Trot, based at 43 Park Ave. and Court Street Park, with runners lining up on Main Street.
- Saturday, December 5, 5 to 7 p.m.: The Hunterdon Holiday Parade on Historic Main Street, with marching bands, community floats and Santa.
The Halloween parade and the holiday parade both pack crowds into Main Street during the same evening hours when the steakhouse starts dinner service and the valet line is busiest. December 5 is a Saturday, when Jersey Prime's dinner hours run latest. It will probably be the first big crowd night after the valet pilot's 60 days are up, so the borough's decision on those three spaces will shape it. As of this writing, no date for a 2026 borough tree lighting has been announced.
The Downtown Groups Are Treating This as a Start
The people who run Main Street describe the reopening as the start of something, not the finished product. TAPinto's reopening coverage reported that Ali Norton, who leads the Flemington Improvement District, said the district is working with the Chamber on seminars to help businesses prepare for the extra foot traffic the hotel is expected to bring. General manager Michael Marino said the hotel plans to work with local merchants and already has several business conferences booked. The hotel also plans event and meeting space for weddings, rehearsal dinners, corporate retreats and private celebrations. Those bookings bring visitors to Main Street on weekends that aren't on any public calendar.
So the Union Hotel you can visit this October is a steakhouse, a steakhouse bar and a second-floor lounge. The game room is still to come, and the parking setup out front will be reviewed by the council. The next things to watch on the borough's calendar are the council's action on the valet spaces around mid-November and an announced date for Fieldhouse Social.
The Union Hotel, the 2025 permit parking ordinances and the valet decision are all changing how the blocks around Main Street work. If you own a home near downtown Flemington and want to know how buyers are likely to see those changes, Jeff Smith at Freeman Smith has followed Hunterdon County's county seat for decades and can explain it in plain terms.
