In a restaurant with no menu, name a soda you'd ask for.
Whatever coke or pepsi I can see over the bar, while wondering why I'm in a restaurant with no menu
I usually just blurt out "cassis", a blackcurrant soda. I for one don't care about which brand. Does that count?
Since the whole Trump thing: Cuba Cola Zero, Champis Zero, Trocadero Zero, Mino Limonata
