Taco Cabana is the clear anchor of Pollo Tropical's similarity graph, scoring 0.71 — a meaningful gap above every other neighbor. The next closest, Eyeglass World at 0.63, is an eyewear retailer, not a restaurant, which signals immediately that this audience's shape extends well beyond the casual dining category.
The top 10 neighbors span six distinct subcategories: Casual Dining (Taco Cabana alone), Eyewear (Eyeglass World at 0.63, Tire Kingdom at 0.63 — wait, correcting by field: Tire Kingdom is Parts and Accessories), General Grocery Stores (Fry's Food & Drug Stores at 0.61, Jewel-Osco at 0.60, La Michoacana Meat Market at 0.59), Apparel General (Burlington at 0.61), Automotive Parts and Accessories (Tire Kingdom at 0.63, America's Tire at 0.59), and Gas Stations (LUKOIL at 0.59). Taco Cabana is the only other Casual Dining entity in the top 10; no other restaurant of any subcategory appears among the remaining nine neighbors. The dominant cross-kind pattern is everyday-errand retail — grocery stores, auto parts shops, a gas station, and a discount apparel chain — rather than food-service competitors.
This spike structure, concentrated at Taco Cabana and then dispersing across unrelated retail and service categories, suggests Pollo Tropical's audience is defined less by restaurant-going habits broadly and more by a specific regional or lifestyle footprint that overlaps with a particular mix of value-oriented, errand-driven brands.
