Jack's Library is a speakeasy cocktail bar on Calle de Santo Tomé, entered through what looks like a flower shop with a door code you get when you book. Inside it's built like an old British library, all books, wood and low light, with cocktails named after writers and artists, and phones and photos are off-limits.

Background

About Jack's Library

The Story

Jack's Library is a speakeasy on Calle de Santo Tomé created by its Scottish owner, Murray MacDonald. The entrance is disguised as a flower shop, and inside it's styled as an old British library.

The Cuisine

The draw is cocktails, mixed with house infusions and syrups and named after writers and artists. It's drinks-led rather than a kitchen.

Jack's Library Dining Experience

Dim and bookish, with wooden furniture, armchairs and shelves of old books. The focus is the cocktails, photos are off-limits, and the mood is hushed and intimate.

Getting There

Jack's Library is on Calle de Santo Tomé, 6, in Justicia, near Alonso Martínez in central Madrid.

Nearby

Centro is Madrid's historic core, the district that holds Puerta del Sol, Plaza Mayor and the long climb of Gran Vía all at once. The eating is dense and varied, from old-school taverns and chocolaterías that have not changed their counters in generations to newer rooms opening along Calle de Alcalá and San Bernardo. Nearly everything in the city is a walk away from here.
