My favourite carbonated soft drink with a unique flvour is Dr Pepper.  Have you ever tried it?
I have tried it, but it's not my favorite. What about it makes you like it so much?
I just love the taste and find it refreshing.  It has been around for a very long time you know, it was first introduced in 1885 would you believe, it even preceded coca cola by one year!
Wow, I did realize that! So Dr. Pepper is a Pepsi product? Do you prefer all Pepsi products over coke products?
Actually no, after Dr Pepper coke would be my next choice. Originally coca cola but renamed coke in 1992.
