Netto- so very close to my house and inexpensive. Fairly well stocked and clean but still sparse, about the size of a large gas station
Superbrugsen- very scattered but more items. Interesting to note that in Europe the shelves are mostly bare expect for about two things of each item. Surprisingly had gluten free pasta and cookies! Finally! (no testament to how they taste however)
Fatka- this is when I truly began to appreciate American grocery stores. This place looked like Walmarts backstock.
Coop- Expensive healthy foods but by far the best atmosphere, music and most clean. Freaking delicious chocolate covered brazil nuts. I feel a new addiction brewing.
By far my favorite snack of the day and made me feel particularly European was my first purchase of "Cocio" chocolate milk in a glass jar. It may have been a drink for little kids but after wandering around to get my id card for two hours this little chilled pick me up did the trick (behind it is Copenhagen City Hall)
