Madrid runs two market economies under one word. The gastro-markets — San Miguel first among them — are tapas theatres for visitors, brilliant and priced like theatre. The working mercados de barrio still sell fish and fruit in the morning, then flip after 13:00 into the cheapest good lunch in the city.
The strategy writes itself: photograph the first kind, eat in the second. Every central barrio keeps a working hall within ten minutes of the hotels.
Mercado de San Fernando in Lavapiés is the model: grocers until noon, then counters — craft beer, fresh pasta, Senegalese plates, a bookshop selling by the kilo. Antón Martín (Huertas) hides serious Japanese and old-school freiduría behind its produce rows; Vallehermoso in Chamberí is where the food press goes when it stops performing.
La Cebada (La Latina) stays rough-edged and cheap next to the Rastro circuit. In all of them the pattern holds: order at the counter, eat standing or perched, pay a barrio price.
The wrought-iron hall beside Plaza Mayor is Spain’s most visited market and prices accordingly. Go at 10:00 when it opens quiet and beautiful, take the photographs, spend one round on a vermút and a couple of bites — then walk away for lunch.
Treat it as a museum of the tapa with entry by consumption. The same money buys a full counter lunch two barrios south.
Markets solve the traveller’s two worst meals: lunch (counters from 13:00, no booking, solo-friendly) and the picnic (bread, cheese, fruit, conservas for the Retiro or the Templo de Debod sunset). Most halls run Monday to Saturday and sleep on Sundays — plan the Rastro Sunday around bars instead.
Booking a hotel near a working market is a quiet luxury: breakfast fruit, €6 lunches and dinner supplies downstairs. Lavapiés, Huertas and Chamberí make it easiest.
