Amsterdam Menus · The Dossiers

The technical layer behind the capstone essay, one dossier per angle

Published

The methods and evidence behind The tourist trap costs 85 cents: seven dossiers, each written as the investigation it was, with the stress tests visible. Corpus: Snapshot · June 2026, ~900 priced venues, roughly 4 in 10 of Amsterdam’s ~2,028 restaurants.

How the dossiers fit together. D1 gives every dish an address (the coordinate system). D3 prices each address: a typical and a 90% range. D4 splits all price variation into dish-type (59%), venue (17%) and item noise (24%); D3’s ranges are exactly D4’s non-dish 41%, displayed cell by cell (see D4, “the ladder and the rungs”). D5 shows the location slice of the venue part is real but small (+4.2%/SD), and D7 confirms it with a model-free commodity check. D6 splits the venue part further: two fanciness registers, with the premium concentrating where no reference price exists. D2 is the venue typology underneath, honest about being infrastructure. One corpus, one decomposition, seven views.

# Dossier One-line punch
D1 The dish coordinate system Every dish gets an address; names lie, coordinates don’t
D2 The venue typology Infrastructure, not discovery, and honest about it
D3 The going-rate atlas Carpaccio is €15 in this town (€11.50–23, 90% of the time)
D4 What moves the price The plate is 59% of it; the room, 17%; the address, a rounding step
D5 The tourist tax Real, +4.2%/SD, and smaller than everyone believes
D6 The fancy tax The premium lives where there is no reference price
D7 The Bitterballen Index Order eight in the centre, pay for nine
