In Barcelona there are a lot of many small cafes, bars, restaurants (located generally in zones where the terrain is very expensive) that got purchased by Chinese families.
Generally these were frequented for coffee, drink + tapas, lunch meal. But after the ownership change they end up frequented mainly for the same stuff but not for the food because it's generally not good.
To me these are front for something else. They always become much worse for eating. Never better. Like there is no intention of improving it. But they still do it smartly because they keep some customers just for the beer and coffee mainly after work.
