Tommy's Express Car Wash sits at the top of Steak 'n Shake's neighbor set at 0.92 — not another restaurant, not a competing fast-casual chain, but a car wash. That cross-kind lead is the defining structural fact of this data.
The shape is broad: scores run from 0.92 down to 0.86 across the top 10 with no sharp drop-off, meaning many entities share meaningful audience overlap with Steak 'n Shake rather than one dominant cluster pulling away from the rest. The top 10 span five distinct subcategories. Two are Car Wash and Detailing — Tommy's Express Car Wash (0.92) and Club Carwash (0.90) — making that the single most represented subcategory in the set. One is Gas Stations: Speedy Cafe at 0.90. Two are Athletes: Baker Mayfield (0.88) and Pat McAfee (0.88). One is Bookstores: Books-A-Million at 0.88. One is Professionals: Urban Meyer at 0.88. One is Casual Dining: Fazoli's at 0.87. One is Grocery and Superstores: Meijer at 0.87. And one is Sports Teams: Notre Dame Football at 0.86.
Only one neighbor — Fazoli's — shares the Restaurants & Eateries category, and none shares Steak 'n Shake's own Fast Casual Dining subcategory. The audience's shape is defined far more by car washes, fuel stops, Midwest retail, and sports-adjacent figures than by the restaurant competitive set.
The breadth and cross-kind composition here point to an audience whose shared traits cut across everyday errand-running, regional retail, and football fandom rather than any single consumption category.
