I like vodka flavored vodka and coffee flavored coffee!
vanilla vodka mixed with coke is really the only kind of vodka I don't despise.
Just regular. The best I have found -- and I do not generally like vodka -- is Charbay. They know what they are doing if they can make me like it, and they have.
Raspberry....mixed with Godiva white chocolate liqueur.
Root beer, or the old stand by no flavor added
I prefer it not to be flavored.
