What kind of drink with a Cajun dinner? (Alcohol!)?

We’re having a Cajun themed cook out and we can’t figure out what kind of alcohol to have with it. Mixed or shots or whatever, what goes?!

these people only drink beer, so any american bottled beer would be OK.

The way the beer is served is they get a big insulated plastic box called a "cool box". Then they fill this with crushed ice and place the beer in the ice. They have a "thing" about warm beer, they can only drink cold beer for some reason. -and they always wrap something round the bottle so their hands don’t get wet.
