best ice-cream parlour/ice salon in Vienna, Austria open all winter

Great news for people spending the winter in Vienna, Austria: Perizzolo, IMHO the best ice-cream parlour/ice salon in Vienna, Austria this year will be open all winter. Normally they close at the beginning of fall and reopen sometime around the beginning of spring. They are located at Tuchlauben 15 and their ice cream is second to none.
