Some of them are. For the week of 20 September 2026 to 26 September 2026, the item that rose at the most restaurants we already priced is McChicken at McDonald's: typically $2.00 to $2.39 at 478 restaurants. That is a same-store reading, not a national average, and it is the kind of move a CPI series cannot name.
Week of 20 September 2026 to 26 September 2026. Archive begins 1 September 2026, and cannot be backfilled.
Search results for “fast food prices up” are usually a press release or a memory of last year’s combo. This page is a count: restaurants we priced on both sides of the week, items that still cost more at the end of it, and the ones that do not. The archive behind it is 26 days old. A price nobody wrote down that morning is gone, which is why the collection runs whether or not anyone is reading.
Typical price among the 478 McDonald's restaurants that changed it this week. The middle of the move, not the most expensive restaurant we saw.
Net of the week, so a limited-time price that came and went does not masquerade as a list-price increase. The week report is the same table with the cuts included and a link to each day.

The price map is what each item costs today, restaurant by restaurant. These pages are what changed. The two answers are not the same, and publishing only the first one is how a price site goes stale.
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 20 September 2026 to 26 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.
