Fountain Coke
A glass of Pepsi I bought at Mel's.
I am a big fan of Coca-Cola. Probably the best way to drink a coke is in a glass with ice. I would say the best source for Coca-Cola is from a glass bottle, though you pay a premium here. I usually buy cans of coke, as they are readily available and taste good. I would avoid plastic bottles of coke as they seem to be flatter then the coke that comes from cans and glass bottles. Now, another beast entirely is fountain coke. Fountain coke is awesome. Even if it's Pepsi, as pictured above.
