Barcelona’s tapas bar side of the legendary Adrià cuisine is a grand collaboration of Albert Adrià with his brother Ferran. Their ultra-upscale 41[dg] Experience, where 16 diners per night pay 250€ and up to eat 50 one- to two-bite morsels, is adjacent. Tickets, frankly, is more fun. It consists of six themed tapas bars in one colorful space. La Presumida is the Mediterranean bar, with its oysters, shrimp, crabs, and razor shell clams. La Estrella is a beer bar serving ice-cold Estrella Damm. The Camarote de los Marx (the Marx Brothers’ Cabin) is a tiny, wacky bar with tapas themed to men as swine and women as ladies of the night. (It helps to speak Catalan to get the jokes.) Nostromo 180286 is where the famed Adrià penchant for invention is given full rein. Most tapas here are variations of sushi and something more traditionally Spanish, such as chorizo. You might get Manchego cheese ice cream or artichokes with smoked Idiazabel cheese and mullet roe. El Garatge uses pa amb tomàquet as a point of departure, offering such tapas as grilled bread with grilled watermelon and pineapple. The final bar, La Dolça (the sweet girl), is for sweet tapas, which are Albert’s specialty. It is designed to make diners feel like kids in a candy store. Alas, there are only 80 seats per night and reservations can be made up to 2 months in advance, but only via the website.
