Urban decor, like quote blocks (Interserve Outcomes) is cute and decreate for the event. I'm guessing the point of the cafe is so that there are relaxed vibes, and every little bit of information isn't thrown into your face when you walk past. it should be inviting-so small comment plaques around help with the subliminal message-people are more likely to think about the message if they see it on something fresh.
I like that candle one. Mostly because I actually do know how candles are made. And thanks to an episode of criminal minds, I know how to draw essential oils that human skin produces naturally and collect it as well. So. Human candles..... wow. What have I written.
