Botin Restaurant in Madrid has been in operation for 293 years, a world record. The owners claim the oven hasn't once gone out. The house specialty is roast suckling pig, which is 25 euros.
Ever since the doors opened in 1725, the oven has been sizzling continuously, never to be extinguished. According to deputy manager Luis Javier Sànchez Alvarez, the oven is the crown jewel of the restaurant and the fundamental element of their most popular dish, the roast suckling pig. The recipes used today have been passed down from generation to generation, keeping the legacy of these traditional dishes alive. With the honor of being the oldest restaurant in the world, Alvarez hopes to keep the doors open for centuries to come.
