i used to go to a very small dunkin near my job they would have it all year round. i make coffee at home now mostly its much cheaper but i miss it. gonna have to just buy the syrup but i fear it wont be the same.
Honestly it's pretty damn similar, I was oddly enough given McDonald's Pumpkin Spice syrup in bottles last year and it went well with my homemade coffee (one of my oldest friends is a GM)
