Casa Pedro is a small restaurant in Madrid, Spain. It says it may be older than the famous restaurant Sobrino de Botín. Botín has a Guinness World Record as the world’s oldest restaurant. It has been open since 1725. Many tourists visit it. Casa Pedro is outside the city center. Its owners say it started in 1702. They hired a historian to check old records. One document from 1750 shows a tavern and wine cellar in that place. This could help Casa Pedro become a new world record holder.

To get the Guinness record, a restaurant must give strong proof. It must show it has stayed in the same place and kept the same name. A Guinness spokesperson explained this rule. But Casa Pedro lost some old records in the Spanish Civil War. That makes it hard to prove its age. The owners are still looking for more papers. Casa Pedro and Botín both serve old-style Spanish food and are owned by families. But only Botín is famous around the world. Experts say old places like Casa Pedro are important for culture. The final answer will come if more proof is found.
