Sloomoo Institute will open its eighth location in Boston on November 14, 2026. The new site will occupy the former Hard Rock Cafe space at 22-24 Clinton St.
Why it matters
The company is expanding its Boston presence to meet growing customer demand for a full-scale immersive experience rather than the limited retail-only space offered previously. By moving operations to a larger facility, Sloomoo aims to capitalize on its high engagement rates.
The new facility marks the eighth Sloomoo Institute location and requires a starting ticket price of $35.99. This follows the closure of the Hard Rock Cafe at the same site in 2022 after 15 years of operations.
The players
Sloomoo Institute
This company is an entertainment brand that creates interactive, sensory-based experiences centered on slime products.
The details
Sloomoo Institute will relocate all activity operations from its existing MiniMoo space at Faneuil Hall Marketplace to the new address. The company officially secured the lease for the Clinton Street property in January 2026.
Timeline
2022: The Hard Rock Cafe closed its Boston location.
January 2026: The company signed the lease for the new space.
November 14, 2026: Sloomoo Institute opens the new location.
Market Landscape
The expansion follows the broader industry trend of repurposing legacy retail footprints into high-engagement entertainment destinations. This move positions the brand to capture increased foot traffic in the Faneuil Hall area by replacing traditional dining with an active visitor experience.
Visitors can access the new experiential site starting at $35.99 per ticket beginning in November. The relocation means that current operations at the Faneuil Hall Marketplace MiniMoo space will transition to the new Clinton Street facility.
The takeaway
Customers planning a visit should note that the new location offers a full experience compared to the previous retail-focused MiniMoo store. Checking the website for booking availability is recommended as the facility officially launches.
