Although come buy might be popular in some countries but I think there is only one in Berlin, and some other cities in germany (especially from Eastern part) even dont have it. Taiwanese bubble tea is not so popular here in Germany, therefore it is such a breeze finding one, a really good one I mean :) the same can be true for the frozen yogurt in this situation. Anyway, thanks for your comment, and I'll have a look at yours too, its good that we foodie can share our food experiences here, isnt it? ^^
