This infographic made by Statista (Statista.com) shows different food prices in Europe
In 2012 the price of a basket of food (and non-alcoholic beverages) was compared across the EU. The results show that Denmark was the most expensive country in Europe, where the cost of food was twice that of Poland - the cheapest country in the European Union

In general, cheaper food prices in the EU can be found throughout in the Eastern side of the continent. 

In fact, Romania has the second cheapest food prices in the EU, while Bulgaria is third, followed by Lithuania and Hungary
