upright, who cares if cocktail can double as a table. You're using it to play games dag nabbit!
EDIT: crap, just though of something: you're having coffee with a stranger with the on the cocktail table, with a cover over it and casually mention if "they would like to play a little game?" when they finally say "okay" you whip off the cloth and throw it to the ground in one sweeping motion, revealing the cabinet while there's a "swooosh" sound in the background. At that point, you say a one liner like "let's play" or something equally malicious
you would be the coolest supervillain ever...
(...although you would have to play something thats kind of crappy 2p, the kind where you have to go guy-by-guy, instead of a badass fighting game)
