I love the sodas that some people say are medicinal tasting like Dr Pepper, Root beer or anything cherry, basically. I find them way more interesting tasting than just plain orange flavoured or plain lemon flavoured sodas which just taste like fruit to me.
Since I'm from New Zealand though, we don't have anywhere near as much choice when it comes to sodas and flavours. If I want any of those drinks, you can only buy them in cans that are imported. Probably my favourite soda you can easily find here would be coke zero or ginger beer. I envy all the selection you have in the US lol
