Two distinct audience neighborhoods pull on Costa Coffee's similarity graph — one anchored in American casual and fast-casual dining, the other in college football media and evangelical Christian voices — with no other Coffee and Tea brand appearing anywhere in the top 10.
The shape is two-peak. The first cluster is built almost entirely from Restaurants & Eateries: Chicken Salad Chick leads at 0.70, followed by Slim Chickens (0.69), Moe's Southwest Grill (0.67), a generic Casual Dining node (0.66), and Bruster's Ice Cream (0.66). Across subcategories, these five span Fast Casual Dining, Casual Dining, and Bakeries Desserts and Confectioneries — a broad mid-market dining band. Chick-fil-A (0.65) and McAlister's Deli (0.64) extend the same cluster. The second peak is sharply different in kind: Brett McMurphy (0.64) and Timothy Keller (0.64) — a sports Journalist and a Spiritual Leader respectively — sit at nearly identical scores, signaling a second, coherent audience neighborhood that has nothing to do with food. Lane Bryant (0.63), classified as Womens Apparel, rounds out the top 10 and sits between the two peaks without clearly belonging to either.
The two-peak structure means Costa Coffee's audience is not simply "restaurant fans" — it is shaped by two overlapping but structurally distinct communities, and neither of them is the coffee-and-tea category the brand itself occupies.
