The Cine Regio in San Antonio is like a cinema from the good old days having one large screening room with red velvet seats, a gallery and even an old style curtain that opens right before each film.
Once or twice a week they show new movies or classics in their original language with Spanish subtitles (look out for V.O.S.E. for Versión Original con Subtítulos en Español).
There is a small kiosk in the first floor selling drinks and snacks like chocolate and popcorn for the complete cinema experience.
