Observatory · Madrid
This observatory ranks 441 restaurants in Chamberí, Almagro, Arapiles, Gaztambide, Trafalgar and 5 more areas by the average of their Google customer reviews from the last 90 days, adjusted for how many recent reviews each one has. Only venues with 15 or more reviews in that window qualify, out of the 346 in Madrid whose reviews we analysed (34,329 in total). Data as of 22 Jul 2026; updated monthly.
We rank by an average adjusted for the volume of recent reviews:
score = (90-day average × number of reviews + 20 × area average) ÷ (number of reviews + 20)
41 restaurants score at least +0.30 above their all-time Google average over the last 90 days. The 10 biggest risers:
Rise = last-90-days average against the all-time average on the Google profile, with 10 or more recent reviews.
What the reviews of each area say, in aggregate: set lunch menus, terraces, noise, real prices and service.
Each restaurant scores with the formula (90-day average × number of reviews in that window + 20 × its area average) ÷ (number of reviews + 20). Those 20 points of "area average" stop a venue with 15 excellent reviews from overtaking one with 100 just as good. The area average comes from those same reviews: Chamberí 4.60, Almagro 4.41, Arapiles 4.62, Gaztambide 4.67, Trafalgar 4.62 and 5 more areas.
Two possible reasons: it is not in the areas covered (Chamberí, Almagro, Arapiles, Gaztambide, Trafalgar, Salamanca, Fuente del Berro, Goya, Lista and Recoletos), or it has fewer than 15 customer reviews in the last 90 days. With fewer recent reviews there is no honest average to publish.
No. The reviews stay on Google, where their authors published them. Here there are only aggregates: averages, counts and classifications, always with the source ("Google customer reviews") and the data date in plain sight.
Every month. The current data runs to 22 Jul 2026; each update changes the rankings, the area averages and the date shown on every page.
