Chipotle and Izze Grapefruit Soda. I don't know why, but I did that once or twice and now I have a permanent association.

Favorite soda I'd have to say Coke w/real sugar. That can be in Mexican form, Jamaican form, or Passover Form (look for 2-liter bottles with yellow top during that time of year). It used to be nice to occasionally mix with Minute Maid Orange Soda, but alas Coke pulled a fast one and replaced it with sub-par Fanta orange... the New Coke of Orange Sodas. I've been waiting for Coke to follow Pepsi's footsteps and put a real sugar version of its cola out in the states but they won't budge. I've also been waiting for a Lime Coke, but they only think people who like artificial sweetners like Lime. That's what, 3 strikes for Coca Cola's product people? They have issues at that company.

Second, Natural Brew Root Beer is the best I've had. It has a great clean flavor. Virgil's Root Beer is also very good, you can detect all kinds of awesome flavors in there, also a great Root Beer.

Honorable Mention goes to some form of Ginger Beer... Reed's Extra, Jamaican, Trader Joe's, they are all awesome.
