I was part of a party of 2 here and we were able to finish the murder mystery game without any troubles. You do need to be ready to order (and therefore pay for) quite a bit, but they do have some alcohol-free options available for at least some of the drinks on the list required to complete the game, so if you're overwhelmed by the idea of drinking a lot to "win" a game, bring a friend and take your time and you'll be just fine.
