18 London postcode districts, each placed at a representative restaurant postcode: marker size is the district's mean chicken-shawarma price in £, colour is HouseMetric's median residential sold price per m² (generally the latest 24 months). Across the 18 districts, Pearson r = 0.106 and Spearman rho = 0.145 — a negligible positive relationship. Markers are restaurant/postcode point locations, not neighbourhood boundaries.

Method: 18 postcode districts (19 restaurant-level observations; only SE1 has two sampled restaurants, all others one), each district's mean chicken-shawarma price joined to HouseMetric's median residential sold price per m², usually a latest-24-month median — not commercial rent. District-level Pearson r = 0.106, Spearman rho = 0.145; restaurant-level r = 0.098, rho = 0.154. Markers sit at representative restaurant/full-postcode points where available; N1, N3, NW6 and W2 use district/neighbourhood representative points. Postcode districts stand in for neighbourhoods. Menus mix or omit dates (observations span 2022–2026), sizes and delivery-versus-in-store channels; one price is a Reddit report and some sources are older or user-generated. Correlation here is descriptive, not causal. Restaurant-level item detail was folded into map tooltips and links for space.
