We came here at around lunch time and it was half full inside. Their English here isn't very good…read moreso be warned when trying to enter. They try their best to help you which is nice. You order at the bar and pick it up at the bar. You can sit wherever you like basically. We ordered fried croquettes, potato omelet, churros and tomato toast. The churros were our second favourite in Madrid. They weren't hot out of the frier but they were crispy and addictive. The tomato toast was a pass - nothing amazing and didn't have enough garlic. The croquettes came out piping hot. Nice and crispy. The potato omelet was also served cold but it went really well with the bread. I would imagine it was very delicious if it was hot. I would come back to try the other things on the menu as their menu is so big. They have lots of things that you could enjoy as snacks. A lot of locals come here and not a lot of tourists which is nice.

A friend and I stumbled on this gem looking for breakfast and a place to kill some time…read more Full of locals, the cafeteria looked promising, a group of men even moved for us to be able to sit together. We don't (unfortunately) speak any Spanish but the staff were all lovely and accommodating anyway :) We ordered a burger and coffee each, and a plate of churros to share, which all came in at under €5 each and were absolutely delicious! If I ever find myself back in Madrid I will definitely be making my way back here!

Menu del dia here is always awesome! Paella and fish dishes are great. Mostly Spanish people here…read moreso it really helps if you speak Spanish for the waiters.

I had a great work lunch with my coworkers here. The…read morerestaurant has elegant atomosphere and many other clients were wearing ties/dresses, I definitely felt underdressed in my Vans shoes. Oops. We chose a variety of appetizers to share and a main dish each. I think on their menu they had more fish than meat and I think they had a whole section dedicated for red tuna. I have to say, for everything, including the olive oil to dip the bread, there was careful thoughts put into it. We had Watermelon gazpacho, vinegared potato wrapped in Nori seaweed, shrimp fritter, and tiny sandwich that I don't really know what it was. For my main I had tuna tartar with green mustard icecream which I managed to take a picture of. All of them was delicious! Especially I was pleasantly surprised by the watermelon gazpacho which was so fresh and creamy and very good for a summer afternoon. The price range is not for me to have lunch here every other day, but I'd love to come back for a special occasion, or if my boss gets the check... :p

Delicious tapas, excellent wine, very friendly bartender even when the place was packed. Casual,…read morelively atmosphere.

Some friends live on Calatrava, and this is their favorite of the bars/cafes/restaurants on that…read morestreet. 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.
