kevin, as YC design guru, do you think a large sign on the top would be wise? I was thinking of something like a two sided /\ sign on top would increase the amount of signage, and increase the height of the signage. A large sign on top that reads "COFFEE" or similar and can be read from a block away might be advantageous. And if need be, it could fold __ flat when not in use (or when local signage laws prohibit it).
