Visited in January 2018. Open on my third attempt (was closed the two afternoons I tried) but was open late evening. A large choice of both Spanish and various European beers mostly from micros. A top beer venue in Madrid.
Seemed rather small and cramped at first but then I realized that they have a downstairs. It was very busy on the Saturday evening that I visited but managed to snag a chair at the bar. All servers seemed very friendly and spoke good English. Nice selection on tap, they offer a flight, and there are no beers excluded from that. Result! Prices were reasonable. Really liked this place, would thoroughly recommend it!
Nice place. Quite similar in look and feel to The Stuyck minus the seated dining area. Burgers between 7 and 10 euro plus half a dozen Spanish and Mexican dishes...all very affordable. Cash only.14 taps with 4 Spanish craft. Small serves (250ml) price at 3.50 to 4.5o euro and there is also about 25 bottles in the fridge mostly local. Nothing amazing in some respects but must/should be on a Madrid crawl. It's comfortable drinking and that's what counts.
