Jack´s Library

As many reviews mention, this bar’s experience can be split into two parts: the entrance process and the drinks. I’ll start with the drinks, since that’s the easy part. The menu is creative, with a variety of styles and options. Personally, I’d have liked to see some simpler, more straightforward cocktails—but that’s just my taste. What we ordered was well-balanced and flavorful; mine leaned toward the acidic side. The bar's design and decor are top-notch—no debate there. Now, on to the entrance. I understand the whole “mysterious vibe” adds something special for many—especially younger guests—but personally, it didn’t do much for me. Thankfully, we only waited outside for about 15 minutes (I wouldn’t have waited much longer), but standing on the street during a heatwave in Madrid is not my idea of fun. Speaking from a business angle, I think this part of the experience might backfire. Happier, cooler guests might stick around for a second drink. As for me? We had one and felt ready to head home. That said, the staff were great throughout—friendly, attentive, and full of smiles.

This restaurant has a very unique vibe and beautiful design that immediately stands out. Most of the cocktails were excellent. The service was great: friendly and efficient. Prices are very reasonable, especially for the quality and atmosphere. Definitely worth a visit

it’s so gorgeous, it looks like a movie. A slice of life from the 1920s, it’s done as a 1900’s library. As you get in, it’s like a florist. A staff member helps you enter, you have to find a code in a small cluttered but intimate space. Also you have to know the password to enter the door to the place first of all. They guide you and help you to find it. Once the secret door opens, you enter, the aroma of incense that’s been kept for decades hits your nose. You are told the rules, and you follow without problem out of respect for the place. Walking in, it’s a sensation like none other. Wonder, amazement, and curiosity. All of which are cured and soothed by the drinks or looking around. Maps, artifacts, books books books, and potions. Recipes for them too. The soft copper colored lights, taxidermied animals, showcases and the welcoming atmosphere. Your ears are taken off guard by the soft jazz emanating from the walls. Temperature is just right. The alcohol, although expensive, is a journey worth your earthly money. The frozen copper of a Moscow mule, the fresh fruits bought that day in a calvino. You look around at the plumage of birds, feathered pens. This is not simply attention to detail, it’s a clear, precise obsession over it. Curated over what feels to be lifetimes, a wealth of knowledge incomprehensible to anyone under or not under the influence of any substance. Jacks library. A window into another time you can feel, touch, taste and smell.

Jack's library is a very cool speakeasy next to another excellent cocktail bar, The Ficus. The attention to detail in creating the ambiance is fantastic! They have a no-picture/video and no-smoke breaks policy which is refreshing. Cocktails are fairly good, bartenders are attentive and helpful. It is worth the wait, usually between 20-30 mins. 10/10 would recommend!

I believe, this is a place where one would come to experience something new. Something unique. The whole place, is immaculate and looks amazing. I have few of their coctails, and each of them were delightful, full of purpose, every ingredient had it own purpose and mixed together... they were creating a heaven upon our sinful planet, earth. The staff were nicest people I have ever met, and they worked hard to provide TOP notch service. I truly recommend anyone going pass by, to come in and enjoy their time in it.

Unfortunately no pictures can be taken inside but you know what? Much better than way! There is also no network so you can put away your phone, enjoy the music and the surroundings and let yourself be lulled by the absolutely magical (in name and recipe!) cocktails. We got a soseki and a Flaubert, highly recommend both! Come to this place, be respectful of its concept and enjoy the atmosphere it has to offer because honestly, you won’t find something like that in Madrid!

My experience at Jack’s Library was absolutely fantastic, and a huge part of that was thanks to Jaime! From the moment we walked in, Jaime was incredibly attentive and welcoming, making sure we were seated comfortably with a warm and friendly demeanor. Not only was the service quick and efficient, but Jaime also went above and beyond to make our visit special. He noticed how much we were enjoying our snacks and, without hesitation, made sure we had plenty to keep us going, even though most guests only receive a limited amount. That level of thoughtfulness and generosity truly made a difference in our experience! If you’re planning to visit Jack’s Library, definitely ask for Jaime—you won’t regret it!

The BEST bar in Madrid! The cocktails my friends had were delicious, but my elderflower gin&tonic was so refreshing. Can’t wait to come back!
