This is the most useful thing anybody does on WhoozGot. A published price that has quietly gone out of date is invisible to us until somebody who walked in on it says so.
What was wrong?
Proof, if you have it
A photo of the board, the menu or the receipt. It is not required, but with it the correction goes live immediately instead of waiting for a second opinion.
What happens next. We correct the listing, and we email Castle in the Air to say a customer arrived on a price they published and it was wrong, quoting the page we read it from. It is not a complaint and it names nobody. Most venues fix it; some claim their listing off the back of it.
