Coca-cola with grenadine or maraschino cherry mixed in. Puts fountain cherry to shame, and hits the spot every time. Works with Pepsi and Dr. Pepper, too!
My favourite hot drink would probably be the caramel hot chocolate from Starbuck's but I don't really drink hot drinks. My favourite cold drink would probably be root beer or Dr Pepper but I don't get to have them often. The only time I ever see them is sometimes in the international aisle in the supermarkets. In New Zealand they aren't sold regularly.
hot: hot chocolate, mocha, tea, latte, milk (almond and soy) and cappuccinos.
cold: sprite, bubble tea, water, crush (cream and orange) and canada dry.
