Cuba Libre, one of my favorite drinks, is essentially rum mixed with coke, some ice, and a few slices of lemon or lime. Easy to make, yeah? Last night, I asked for a Cuba Libre made with sugarfree coke and I got a Cuba Libre with sugarfree coke, ice, sugar on the bottom of the glass and a sugar frosted lemon wedge? Seriously, what's your damage? And this happened in The Irish Pub, one of my favorite get-together spots.
