Seattle, WA · Seattle, WA
bar-club
No verifiable disco/house bar-club named "The Jack" could be confirmed in Seattle nightlife listings, Yelp, or event platforms. The only matching domain (thejackseattle.com) belongs to an unrelated Pioneer Square office building, not a music venue, so it appears to be a false lead. Dataset entry retained as-is but could not be corroborated with real-world sourcing.
