San Sebastián's tortilla de patatas is the just-set Spanish potato omelette: slow-confit potatoes and onions bound in barely-cooked egg, sliced like a torte and served as a pintxo at every Parte Vieja bar.

The tortilla de patatas is Spain's most-served dish, but the Basque pintxo-bar tradition gave it the just-set (poco hecho) form that defines the San Sebastián version: the egg should run when cut. Antonio Bar on Calle de Bergara (the current owners took over in 1995) is widely cited (San Sebastián tourism, Time Out, Eater) as the city's reference tortilla, taken off the heat with the centre still liquid. Bar Bergara on the same street and La Cuchara de San Telmo in the Parte Vieja keep their own signature versions on the bar all day. The pintxo cut (a thin wedge served at the counter) is the form to order.
