Piggly Wiggly is nice! They have good prices and during the summer months they sell local fruits and vegetables, which i appreciate very much.
With the bread, my colleagues often ask me »What is typically German Food« and all i come back with is the bread. There is really some culture about bread in Germany, we have countless different types of bread and very few people buy it in supermarkets (Aldi!) because the quality there is so poor.
The typical stereotypes of "German" food, the "Bratwurst" with "Sauerkraut" are not typical German. Sausage recipes have been invented all over Europe (Polish Kielbasa and Romanian Carnati, for example) and Sauerkraut is popular almost everywhere. And also beer isn't special for Germany, think about Budweiser from the Czech republic…
But the bread is really unique in Germany! If you ever travel to Germany try a »Brötchen mit Schinken« (Bread-roll with ham)! - Now i'm hungry…
