Two of Jersey City's buzziest food pop-ups are joining forces. Between Two Slices and Sourdough Society plan to open a joint storefront in Jersey City Heights in December 2026, bringing their sandwiches and baked goods together under one roof for the first time.
The planned shop will combine Between Two Slices sandwiches with Sourdough Society's sourdough breads and baked goods, according to Hoboken Girl. The businesses announced the partnership on Instagram, calling it “the greatest pairing since the PB&J.” The owners said they still have work to do before opening but promised more details in the coming weeks.
In the meantime, Sourdough Society will be closed for the rest of November 2026 while it prepares for the move, per the same report. The bakery opened its first physical location in November 2025 and is now preparing for a new storefront.
From Apartment Kitchens to Farmers Markets
Between Two Slices has deep roots in one man's kitchen experiments. Chris Gennone was hired to produce a monthly sandwich column for NJ Monthly in 2020, and by 2022 he'd grown unhappy in his day job and decided to pursue sandwich-making in earnest. He began selling sandwiches from his apartment kitchen to close friends in January 2023, the article notes.
Gennone has said sandwich-making holds nostalgic meaning for him, tied to memories of bonding with his grandfather and father. Between Two Slices now operates as a monthly pop-up, publishing a limited new menu on Instagram ahead of each sale and taking customer pre-orders through an online form. Sandwiches are prepared in a commercial kitchen and distributed at designated pickup locations, with the business also showing up at the Van Vorst Farmers Market and Riverview Farmers Market.
Sourdough Society's Pandemic-to-Storefront Journey
Sourdough Society traces back to married Jersey City couple Sophie and Giota Kolaitis, who started the business after both were laid off from their corporate careers. Giota had picked up sourdough baking as a pandemic hobby, and in 2024 Sophie suggested selling Giota's homemade loaves on Facebook Marketplace. Sophie has said customers began ordering and liked the bread, a response that pushed the couple toward turning the hobby into something bigger.
By January 2025, the sisters had formed an LLC and started selling at local farmers markets, including the Coles Street and Hamilton Park markets. The menu expanded along the way to include sourdough cookies and dog biscuits. That momentum carried Sourdough Society into its first physical location inside Nana's Deli at 210 Hudson Street in Jersey City in November 2025.
That earlier milestone came together quickly: the shop soft opened inside Nana's Deli on November 12, 2025, with a grand opening following on November 28, 2025, according to a separate Hoboken Girl report. A year later, the bakery is on the move again, this time pairing up with Between Two Slices for a shared storefront.
Sourdough Society describes itself on Instagram as Jersey City's sourdough dealer, noting it bakes with a starter reportedly more than 100 years old that originated in Greece. Fans of either business will have to wait for the promised details on an exact opening date, but for now, the Heights has a new food destination to watch for this winter.
