Some friends live on Calatrava, and this is their favorite of the bars/cafes/restaurants on that street. This place is classic Spain, or rather classic Madrid: dark wooden interior with a raised bar manned by well-dressed bartenders, clientele a socioeconomic mix, united by proximity, beer slung beside vermuth and all your traditional cured meat plates and some seafood with the "cecina" standing out as the heavy hitter.
We always end up spending more money here than we mean to. One more plate of cecina, another round of vermuth, another hour soaking in the setting, tossed on the waves of conversation. That's Spain for me, and in that undertow it's hard to escape with your bank account intact. It's not that Casa Gerardo is an expensive place by any means; it's that the place foments prolonged social engagements so characteristic of its host culture. Having a good time costs money!
TL;DR Casa Gerardo is a must-see if you want to be immersed in a typically Madrileño experience.
