I drink diet soft drinks when I drink them (I know, I know); in the diet version, Pepsi's a lot better tasting.
I *love* root beer; used to drink Sarsi (sarsaparilla is one of its main ingredients, hence the name) as a kid in Malaysia. Root beer in general is hard to find in the UK; Sarsi impossible to find. I believe it's a Coca Cola property.
Has anyone been to the Museum of Coke in Las Vegas? Basically it's a giant gift shop, but they do have a bar where they sell Coca Cola-owned drinks of different and bizarre flavours
as a kind of tasting menu.
