In Zürich, there are 3 grocery chains with a major presence, and a fourth that's smaller but influential. Migros is probably the least expensive, with a heavy emphasis on in-house brands. They're roughly comparible to Walmart. They're trying to expand into everything. There are Migros electronics stores, Migros banks, Migros credit cards, and even a Migros mobile phone plan. Denner is a hybrid of convenience store and grocery store. They all seem to be small, though they have a pretty good selection for their size. For many of their products, they only sell the store brand. Coop is a middle tier grocery store. They carry some in-house brands and a lot of the brands that you'd see anywhere in the world. I'd equate them to Target or Giant Eagle. Coop has also started to expand into other markets like banking. Globus is very nice and very expensive. There are only a few of them in Zürich. They tend to have a much better selection of unusual international food...
