The rivalry between two family-owned taverns in Madrid, Sobrino de Botín and Casa Pedro, centers around their claims to be the world's oldest restaurant. Sobrino de Botín, founded in 1725, holds the Guinness World Record, while Casa Pedro asserts it has been operating since 1702 but lacks proof. Both establishments have notable patrons and historical significance, with Casa Pedro currently seeking documentation to support its claim. The competition intensifies with La Campana in Rome, which claims over 500 years of operation and plans to apply for the Guinness title. Teljes cikk (Euronews.com)
