I can definately see these on shirts and hats in both colors. I am not sure how it would work for the sign since they just put lighted letters on the building, maybe without the good food, good fun, good friends. But I really like this.
I can't see it without that slogan above, as it looks like a roof (like "all friends under one roof") and the logo would defenetly change without it. It won't look bad, it will change in some way :)
