Which items show up at the fewest restaurants we have priced — Burger King, Chick-fil-A, Chipotle, Domino's, McDonald's, Papa John's, Popeyes, Taco Bell, and Wendy's, across 50,900. At McDonald's the standout is McRib, priced at 227 of 12,238 restaurants (1.9%).
As of 26 September 2026 · 50,900 restaurants across 9 chains.
1.9% of the 12,238 McDonald's restaurants in the sample. That is the rarest well-known item we can point at without leaning on a one-restaurant leftover.
One notable uncommon item per chain, not always the absolute rarest row — a leftover international SKU at one restaurant is a worse headline than a sandwich you might still walk in and order.

Each page ranks that chain’s own menu against its own sample. A rare item at Taco Bell and a rare item at McDonald’s are not the same kind of rare — the denominators differ.
One restaurant can be a test market, an airport, a theme park, or a row the US ordering feed was never meant to serve. That is why each chain page splits three-or-more restaurants from one- and two-restaurant sightings. The interesting rare items sit in the first list: a McRib, a regional chicken sandwich, a leftover Taco Bell that a handful of restaurants still sell.
Typical prices, not rare ones, are on the cheapest items and on each chain’s menu-prices page.
