Mor Furniture for Less sits at the top of Port of Subs' similarity graph at 0.69 — a furniture retailer as the nearest neighbor to a sandwich chain is the structural headline here. The shape is two-peak: one cluster anchors around convenience and fuel, the other around that furniture outlier, and the two neighborhoods are meaningfully distinct.
The convenience-and-fuel cluster is dense. Terrible Herbst (0.67), Rebel Convenience Store (0.67), ampm (0.65), and Fast Market (0.63) are all Convenience Stores by subcategory, forming a tight band in positions two through five. That cluster makes intuitive sense as a regional, everyday-errand audience shape. What makes the two-peak structure is that Mor Furniture for Less sits above all of them — a Furniture Store pulling a higher similarity score than any convenience brand in the set.
Beyond those two peaks, the remaining top-10 neighbors spread across Casual Dining (Taco Cabana, 0.60), Entertainment (SeaWorld, 0.59), General Grocery (Fry's Food & Drug Stores, 0.58), Sporting Goods (Academy Sports + Outdoors, 0.58), and QSR (Whataburger, 0.58). Only two of the top 10 — Taco Cabana and Whataburger — share a Restaurants & Eateries category with Port of Subs, and neither shares its Fast Casual Dining subcategory. The audience shape here is defined less by what Port of Subs is than by the regional, multi-stop errand profile of the people who visit it.
