Cincinnati Zoo sits at the top of Skyline Chili's similarity graph at 0.95 — not another restaurant, not a sports team, but a non-profit cultural institution. That's the structural signal the two-peak shape is built around: one peak anchored by Cincinnati civic institutions, a second anchored by Ohio and regional sports.
The first peak runs through Cincinnati Zoo (0.95), Rhinegeist (0.93), and Graeter's Ice Cream (0.92) — a non-profit, a brewery, and a fellow restaurant brand, all tightly clustered and all Cincinnati-rooted. The second peak is built from sports teams and athletes: AJ Green (0.87), the Cincinnati Bengals (0.87), the Cincinnati Reds (0.86), and Brandon Phillips (0.86) form a dense block, with Ohio State Football (0.82) and the Ohio State Buckeyes (0.80) extending the sports cluster beyond Cincinnati proper. Among the top 10, only Graeter's shares Skyline Chili's Restaurant subcategory; the rest are non-profits, breweries, sports teams, and athletes — a cross-kind pattern that defines the shape. McNeil (0.82), classified as Miscellaneous, is the one neighbor that fits neither cluster cleanly.
The two-peak structure points to an audience that organizes around regional civic identity as much as around sports fandom — two distinct but overlapping loyalties that converge on this brand.
