How this is counted. Only a restaurant we priced on both sides of the comparison counts as a change — the same rule as same-store sales. A restaurant or an item we had never priced before is new coverage, not a price change, and is not in these tables. Figures are as of 21 September 2026. Typical prices are the median among the restaurants that actually moved, not among the whole chain. A jump larger than threefold is dropped as a likely mismatch.
