As the town of Villarreal isn’t too large you can explore a variety of eating and drinking options before/after the match with the Plaza Mayor where the city hall is being a good starting point.
Bars are in an abundant supply such as Casal Del Futbol (Villarreal supporters club) or Restaurant Ca Alex and many serve Tapas which can make for an excellent snack.
קיצר צריך מרכז העיירה זה המקום הכי נורמלי
