Exbayern, many thanks for your excellent posts. THe Sahnesteif is indeed a very excellent suggestion. Mine is empty and I forgot to replenish. Will have my mother send some. Didn't know about most of the other things you wrote about. Very interesting for Albrecht owned Trader Joe's and hazelnut filled Mon Cheri as well as the Uberraschungseier. Very American on the latter two. Alcohol filled chocolates could be abused by alcohol craving teenagers and serve to circumvent the strict liquor laws and Uberraschungseier might actually kill somebody who'd be due for a Darwin award.

I once read in the signature line of a forum member something to this extend:
"How to get rid of most problems in the US? Just do away with all the product warning stickers and the problem will take care of itself."

Very mean but not untrue.

And thanks to the Karstadt at Hermannplatz and Markthallen suggestions. Will pass that on to my mother who is new in Berlin.

Till
