Chevron Extra Mile sits at the top of In-N-Out Burger's similarity graph — a gas station convenience brand, not another burger chain — with a score of 0.92. That cross-category lead sets the tone for a broad neighbor set that spreads well beyond quick-service restaurants.
The shape is broad: scores run from 0.92 down to 0.86 across the top 10, with no single neighbor pulling far ahead of the rest. 24 Hour Fitness (0.91) and El Pollo Loco (0.90) follow closely, then The Habit Burger Grill (0.90), Mountain Mike's Pizza (0.89), Yogurtland (0.89), Miniso (0.89), Carl's Jr. (0.89), The Flame Broiler (0.88), and Mandee (0.86). By subcategory, the top 10 includes three QSR brands, three Fast Casual Dining brands, one Fitness Centers and Gyms, one Gas Stations, one Department Stores, and one Womens Apparel — a genuinely mixed composition. Only four of the ten share In-N-Out's own QSR subcategory.
The cross-kind presence of a gym chain, a gas station, a retail department store, and an apparel brand in the top 10 signals that this audience's shape is defined by something broader than food-service habits alone — it maps onto a regional, everyday-errand consumer pattern rather than a fast-food-specific one.
