Outback used to have a gingerbread flavored one that was too sweet for me. I can't think of many others that are holiday themed.
What about you, do you like holiday themed drinks?
Egg nog would be lovely right now!
We make green whiskey sours for St. Pat's, and they're amazingly delicious! I'm a big fan of anything holiday themed, actually, but that's definitely my top pick. I also really like the orange Bacardi Breezers with vanilla ice cream and chocolate syrup, which I do especially around Halloween.
