Antagonistic game (Zero-sum game)

Two friends want to spend their weekend together. They are choosing between a bar and a theater. One friend prefers a bar and the other prefers a theater. If friends go to the place of their preference alone, they spend time moderately well. If friends somehow turn up alone in a place, which is not preferred, then their weekend is utterly destroyed. If they both go to the same place, then they spend a great time together. So, it would be better for both of them, if they cooperate. Is this game zero-sum?
