The much-honored Spanish restaurant elBulli, which closed in 2011, was once considered the best in the world, but this intriguing foodie documentary reveals a rival - a sibling rival, that is. While elBulli's head chef Ferran Adriá was proclaimed a genius, it seems that behind the scenes simmering wasn't confined to stockpots. Over a four-year period, filmmakers Collado and Loomis follow the story of Ferran's former partner and co-chef, younger brother Albert, as he steps out of the long shadow of elBulli's legacy and stakes his own claim to fame on an ambitious string of five restaurants in Barcelona's theater district, each featuring a different wildly innovative cuisine. Mouths will water as the film details the creation of Enigma, the seriously experimental eatery that Albert hopes will seal his place in gastronomic history.

Chicago: Opens Aug. 24 at the Siskel Film Center.
