This restaurant advertises itself as being open 24 hours a day. Yet I've been through twice in the early AM (~4AM - 4:30AM), only to be told that their systems were being rebooted and they couldn't take my order. No provisions for taking an order the old fashioned way -- just flat out "we can't take your order".
You're either open 24 hours or you're not. Don't advertise something you can't deliver on.
