Water in your wine

Well, I know the internet is nice, but I would still like to buy my wine, beer or spirits directly from the store. Do I know the Munhowen Vinotheques? What are wine libraries? It's like a grocery store, is that it? Have you been there? So what ? So if I sum up they have 3 wine libraries (Strassen, Hesperange and Kirchberg), in each of them I could find a wide choice of wines, beers and spirits. They have very good advisers if you ever feel lost in all this diversity. They also have very good bottles and they always have something new to present to customers. Seriously? How could I not have heard of it? You will take me there, I have some purchases to do suddenly.
