Café Price Index
Dataset: Q4 2024
The price of an espresso is the most accurate real-time indicator of neighborhood gentrification and tourist density. French law requires cafés to display their prices for three distinct zones: au comptoir (at the bar), en salle (at a table inside), and en terrasse (outside).
| Arrondissement | Au Comptoir (Bar) | En Terrasse | Tourist Markup (Delta) |

The Protocol: To drink coffee like a resident, walk directly to the zinc counter, order "un expresso", drink it standing up, leave €1.20 in coins, and exit. Sitting on the terrace transforms the transaction from a caffeine delivery mechanism into a real-estate rental.
