I will be in Tallinn on Christmas on the 24th and 25th. I know many places are closed but what are most likely open. I am really asking becayuse it seems se be very cold so finding some shops, cafes, or anything to go in and get warm would be nice. Im mostly thinking about old town. I know that in the harbour area were my hotel is that Statoil station is open and of course ferry terminal. But what about like near the big square?
