(CNN) — Looking for the coolest spot in Barcelona, Spain? Try behind a fridge door. El Paradiso is a clandestine little speakeasy hidden behind a wooden door out the back of the Pastrami Bar deli in the Catalan capital's El Born neighborhood.
It's headed up by award-winning mixologist Giacomo Giannotti, named Spain's World-Class Bartender of the Year in 2014, and it serves some of the finest cocktails in the country.
Cocktail in a box: Barcelona's Hidden Treasure
When CNN was in town for the Barcelona episode of travel series "In 24 Hours," the Italian-born London-trained Giannotti showed us how to make his Mediterranean Treasure cocktail (El Tresor Mediterraneo).
It's a sour-savory cocktail inspired by his adopted hometown of Barcelona.
The flavors of land -- elderflower, honey, the citrus freshness of coriander -- are balanced with the seawater tang of oyster leaf and crisp, clean fino sherry.
For that extra touch of maritime finesse, El Paradiso serves it in an seashell inside a treasure chest.

- 20 ml fino sherry infused with oyster leaf
