Where can I get Yule log cakes from?

As you all know, Yule Log is a Christmas dessert that resembles a Swiss roll and is filled with butter icing, and has a coating of either butter icing or Ganache. Does any one of you (especially the foodies) know where I can get good quality Yule logs having the above ingredients? I used to have such a Yule log at the Christmas and Christmas eve buffet dinners at avenue regent, mg road, for some of the past few years, it was delicious, but I cannot afford to go there again, that too with the sole aim of having this cake. If you guys know where to get good quality Yule logs from, please let me know!!
