At the top of Zaxby's similarity graph, an automotive service chain sits nearly level with a restaurant: Express Oil Change scores 0.90, just a hair above Waffle House at 0.89 — and that pairing defines the two-peak structure of this audience.

The top 10 splits into two recognizable clusters. One is automotive and vehicle services: Express Oil Change (0.90), Take 5 Car Wash (0.88), and Joe Hudson's Collision Center (0.84) together account for three of the ten slots. The other is casual and regional dining: Waffle House (0.89), Bojangles' (0.88), and — further down — the broader food-and-retail tier represented by Belk (0.88) and TrustMark (0.86). Neither cluster is a close match for Zaxby's own subcategory of Fast Casual Dining; the two restaurant neighbors are classified as Casual Dining, not Fast Casual. The remaining three neighbors — athlete Inky Johnson (0.85), author Thom Rainer (0.84), and spiritual leader David Platt (0.84) — sit at the lower end of the top 10 and point toward a distinctly Southern, faith-adjacent audience layer that neither cluster fully captures on its own.

The two-peak shape here signals an audience that bridges routine service consumption and regional dining culture — two behaviors that don't obviously overlap but converge sharply around this brand.
