The Sloomoo Institute is set to open a 17,000-square-foot, slime-themed attraction in the former Hard Rock Cafe space at 22-24 Clinton St. on November 6, 2026. The facility, which is currently hiring for 100 positions, arrives in the Boston market following the success of a smaller pop-up in the area.
Why it matters
The repurposing of the large-scale Clinton Street storefront marks a significant shift in the Faneuil Hall retail footprint toward experiential tourism. For local operators, the expansion highlights the continued demand for high-capacity, interactive venues that drive foot traffic in legacy commercial districts.
The new attraction spans 17,000 square feet and is currently hiring for 100 positions to manage the facility. Tickets for the experience are priced starting at $35.99 for general admission and $65.99 for VIP access.

Timeline

November 14, 2026: A grand-opening celebration occurs.
Market Landscape
This development follows the June 2022 closure of the Hard Rock Cafe, which occupied the address since 2007. The transition reflects a broader shift in the Faneuil Hall area from legacy full-service dining toward experiential attractions designed for high-density tourist traffic.
Business owners in the Faneuil Hall vicinity should prepare for increased pedestrian density and evolving customer demographics starting this November. Operators should monitor how this high-capacity, interactive model influences peak-hour traffic and local retail spending patterns.
The takeaway
The arrival of a large-scale sensory attraction signals that vacant restaurant real estate in prime tourist hubs is increasingly being targeted for interactive experiences. Operators should track local foot traffic data to determine if this new facility creates a broader lift for the surrounding district.
