File this promotion under “too creative for its own good.” This restaurant tried to create an interactive business card that shows its information after being warmed up. Realistically, how many people want to spend their time warming up business cards when they want a phone number? It’s definitely an interesting approach, but I’m not convinced that it’s practical. It’s important to be creative when you can, but when your message gets lost in the product you know you’ve gone too far. They should have done a custom business card holder instead.
