Like Scott said it is
Kahlua
Vodka
Soda
-- I know soda some places means what pop or cola means other places, but in
this case, and if you see it in a recipe it means plain carbonated water ot
seltzer water.
Since you drink it so fast it probably won't matter if you use tonic or soda
water, but tonic had quinine in it so it has a much different flavor.
-- As for being a shooter or drink, it's naturally up to the customer how it
is consumed. If you are a bartender/server and are concerned about the price
to charge, ask your manager.
