What's New Around Grand Junction Plaza This Fall: An Evening in Downtown Westfield

Stand on the Great Lawn at Grand Junction Plaza and look north. The buildings across Jersey Street are no longer under construction. Sun King Brewery held its grand opening at 133 S. Union St. on April 24, 2026. Current in Westfield reported that the opening completed the development on the north side of Jersey Street facing the plaza.

That changes how a night out downtown works. Coffee, a brewery with two food concepts, pizza and an ice cream shop now sit on one block across from the lawn and amphitheater. On Friday, Oct. 23, the city's Trick-or-Treating in the Plaza returns. It will be the first Halloween event at the plaza since Sun King and Stella's Ice Cream opened.

The block that filled in

The Union is the mixed-use development north of Grand Junction Plaza, bordered by Indiana 32 and Mill, Union and Jersey streets. When Current in Westfield covered its tenant announcement in July 2025, the paper listed seven names and said opening dates would depend on construction and build-out. The City of Westfield's announcement listed the same roster.

Over the next year, those names became real storefronts. Sun King was the biggest addition, and Mayor Scott Willis was direct about why it matters to the city. At the April 23 ribbon-cutting, he said the top destination for Grand Park visitors had been Sun King's Carmel location. He described the new Westfield spot on State Road 32 as a "blocking position" to keep those visitors in town.

Sun King co-founder Clay Robinson spoke about the view. "When you get upstairs, it's probably more than a million-dollar view," he told Current. Upstairs is Upper House Social. Stacked House is on the first floor, according to Sun King's Westfield page.

So a project that started as a tenant list now faces the plaza as a finished block. Most of the businesses share one address.

170 Jersey St., suite by suite

Three of the confirmed-open businesses list 170 Jersey St. as their address. Here's where things stand, based on the most recent sources available:

Stella's is the newest. The shop opened July 1, in time for the July 4 weekend, and held a grand-opening celebration July 11. According to Current's opening story, all the ice cream is made in-house. Stella's offers 10 regular flavors year-round plus dairy-free options, and general manager Briana Edwards said the shop can handle special dietary needs.

The shop also welcomes dogs. A bulldog figure greets customers at the door, and Stella's sells puppy treats for people who come in while walking their pets. If you're feeling ambitious, there's the Dog Bowl Challenge: one scoop of each of all 16 flavors, served in a dog bowl with whipped cream, sprinkles, chocolate sauce and a cherry. It costs $50 and is free if you finish it within an hour. Winners get a T-shirt and a photo on the shop's Hall of Fame.

The Spark has been there the longest. It held its grand opening Aug. 8, 2025, about eight months before Sun King opened. BlackSheep's Westfield page takes reservations and online carryout orders, which helps on busy plaza nights.

H Steakhouse at 207 Mill St. rounds out the corner. A Feb. 1 Current story reported a planned Feb. 7 opening for the restaurant, which is owned by veteran restaurateur Henri Najem. By mid-April, Current listed H Steakhouse among the restaurants occupying commercial space at The Union, on the southwest corner of Jersey and Mill streets.

Oct. 23 puts the whole block to work

The plaza has had a full year. Jams at the Junction filled the Great Lawn on five summer Fridays from June 26 through Aug. 28, 7 to 9 p.m., according to the city's May announcement. The rescheduled Westfield International Festival followed on Sept. 19. The next big event is Trick-or-Treating in the Plaza.

The city announced the details on Oct. 6. The event runs Friday, Oct. 23, from 4:30 to 8 p.m. at Grand Junction Plaza, 225 S. Union St. NSpire Church is presenting it, and admission is free. More than 60 local businesses and organizations will hand out treats to kids of all ages. Costumes are encouraged but not required.

Here's what's planned around the plaza that evening:

• Amphitheater: a magician performing four shows over the evening
• Throughout the plaza: live dance performances, a silent disco and free face painting
• Carnival games: a $10 Ghoulish Game Card covers the games, and proceeds go to Family Promise of Hamilton County
• History: a ghost tour through Old Friends Cemetery and other historic parts of downtown Westfield
• 6 p.m. on the Great Lawn: an outdoor screening of Goosebumps, so bring blankets and lawn chairs
• Giving back: Versiti Blood Center is running a blood drive, and the city recommends booking an appointment ahead

There's also a donation drive for Family Promise of Hamilton County. The city lists the group's five most-needed items as canned foods, all-purpose cleaner, hand soap, Clorox wipes and body wash. You can drop donations at the NSpire Church booth.

"Trick-or-Treating in the Plaza is a fun, safe way for families to celebrate the season, make memories and enjoy time with neighbors," Mayor Willis said in the release.

The schedule lines up with the businesses across the street. The event runs three and a half hours, and the movie starts partway through. That leaves a window between trick-or-treating and the 6 p.m. screening. Pizza from BlackSheep, a meal at Stacked House or a cone from Stella's are all a short walk from the lawn where you'll set up your chairs.

Getting there and parking

The parking details reflect how much downtown has grown. According to the city, you can park free in designated on-street spaces on Union and Mill streets and in the public lots at Park and Poplar streets. The Union garage is free for the first three hours, then charges a small hourly fee.

Three hours covers almost the whole event. If you arrive at 4:30 and stay through the end of the movie, you'll probably go past three hours in the garage. Pick a street space or one of the public lots if you plan to stay late.

You can also skip downtown parking. A free shuttle will run throughout the event between the Westfield Washington Public Library at 17400 Westfield Blvd. and Grand Junction Plaza.

Still on the way

Some downtown projects were announced but haven't been confirmed as open in any source available as of early October 2026.

Broad Ripple Seafood North and Bar was planned for the former Greek's Pizzeria site at 31 Park St. In February 2026, Current reported that demolition was expected that month and that the owner hoped to open by mid-April. No later report has confirmed an opening, so treat the restaurant as planned until you see it open.

Three other names from The Union's original tenant list are Pure Barre, Everbowl and Woof Gang Bakery and Grooming. None of them has a confirmed opening date or suite address in the sources reviewed for this post. Current's Sun King story also said more development is planned around the plaza and nearby Park Street.

After the costumes come off

The next confirmed date on the plaza calendar is Westfield in Lights on Dec. 5, 2026, listed at Grand Junction Plaza by Visit Hamilton County.

The Ice Ribbon is the other winter event to watch, though the city hasn't announced dates for 2026–27 yet. Last season ran Nov. 22 through Jan. 3, according to a Nov. 7, 2025 city notice. Sessions lasted 90 minutes and required advance reservations. Tickets were $12 for ages 11 and up and $10 for ages 10 and under, skate rentals included. Those details are from last year. Wait for the city's new announcement before you plan around them.

If the rink comes back on a similar schedule, it will be the first skating season with Sun King, Stella's, The Spark and BlackSheep all open across Jersey Street. Last season, Sun King and Stella's weren't open yet.
