I love this site.....planning first big Central European trip in the Dolomites/Slovenia/Hungary etc. The info on here is fab.....great link, thanks chaps for taking the time to post.
Enjoy your stay in Vipiteno! I had researched where to buy Parmigiano Reggiano cheese there when I was passing through last summer. Google street map, co-ordinates, shop front photo - the lot. When I got there (up a narrow one-way cobbled road) it had turned into a shoe shop!!!!
