Methodology

Our methods depend on the question. An operator’s website can establish what the operator publishes and where it tells customers to look. A published menu can establish a listed price on the day it was read. Neither establishes where a truck is now, what it has in stock or what a meal will cost at the window.

Operator source records

For each operator we read its own website and record where it publishes its schedule (a calendar page, a weekday page, a named social profile, or none found), its menu, its booking page and any preorder link, with the date checked and the page each fact came from. A missing channel is recorded as not found in the checked pages, which means we did not find it, not that it does not exist. Social profiles are linked only where the operator’s site points to them; their posts are not read or reproduced.

Price baskets

Lunch comparisons use named items from specific published menus and state what each basket includes. The arithmetic is done by a printed calculator that is run as shown. Tax, fees, portions and availability are recorded as unknown unless the source states them, so a basket is a listed-price comparison, not a predicted bill.

Catering terms

Catering comparisons record each vendor’s published minimums, fees, travel terms and inclusions from its own pages, with unknowns kept explicit. Quotes are compared only on matched guest counts, duration and inclusions. No quote was requested and no booking was made; identities we could not confirm from a primary page are marked unverified.

Transit context

Station distances are straight-line calculations from official entrance and venue coordinates, run twice from packaged snapshots. They are not walking routes or current entrance conditions.

Tools

The operator finder filters a static table in your browser. It makes no network requests while filtering, asks for no location and stores nothing. Its behaviour was checked in a real browser and the record is published with the data.

What we publish

Compilations are CC BY 4.0, and original code is MIT licensed. Each asset’s METHOD file, hash list and source ledger are published with it. Those licences do not relicense operators’ menus, text, photographs or any official data.
