One of the least expensive options to buy food in the area. It’s quite clean and I didn’t notice any misleading info(another reviewer mentioned that on Unilocal months ago). They probably fixed those problems by now. The shop is exactly what one would expect from a grocery discounter — basic assortment of food and drinks at affordable prices. They even sell some organic stuff. There’s a very hot oriental sauce, I liked it a lot(forgot the brand name, will update later). Dia used to be part of the Carrefour group for several years but it is now an independent Spanish company headquartered in Madrid.
