I think München is a bit far from all the cities mentioned before :S
I just googled "MarktKauf" but everything is in German and my language level is still low, I've never heard of it before!
it's a malmart im germany, marktkauf
it's also in münchen
so you can see it too, it's a very huge walmart
with a clothing department, a huge store with magazines, books, cds, dvds, games, and gadgets, and also groceries in every brand, and also a restaurant in the walmart itself where you can eat after you shopped because it's a big place with loads of stuff
. reminds me of christmas shopping.
You should defenitely visit, it's cool!
