His restaurant is called Alejandro Serrano, like him, and is located in Miranda de Ebro, one hour away from Bilbao. There he gives value to the Castile Region through the sea. He offers a colorful, creative and fresh experience, as he also wants to make fine dining more accessible to a younger generation that seems to be intimidated by old ways and is just looking to enjoy, discover and be stimulated. He works with local producers to get the freshest seasonal produce and with local young artists to create music, plates and art pieces for his dining room. After several years working in some of the most prestigious restaurants worldwide such as Azurmendi and DiverXO, which both have three Michelin stars, Serrano decided to start his own restaurant. He opened Alejandro Serrano in 2019 in his hometown, Miranda de Ebro, located in the Castilla y León region in north Spain. His innovative gastronomy highlights the uniqueness of "the landscapes of Castilla" and the local products of the region. In December 2021, he became the youngest chef in Spain to win a Michelin Star. He also got a sun in the prestigious Repsol guide in Spain and is a part of the list of 30 under 30 from Forbes Magazine.
