How do you make a churro even better? By stuffing them with guava paste, apple filling, vanilla custard, lechera, chocolate or caramel, that's how! This is the success story of Mr. Churro in Olvera Street. Started by Leticia "Mama Churro" Delgadillo, who immigrated to Los Angeles in the 1930s from Tepic, Nayarit. Mr. Churro has been an Olvera Street staple for locals and tourists alike since it opened its doors in 1974. Located inside the hallway that connects Alameda with the historic birthplace of Los Angeles and open everyday from 9 a.m. to 8 p.m., just look for the crowd of people carrying foot-long golden logs filled oozing with colorful fillings.
