One week without internet, If I knew in advance of it happening, I would buy a hotdog cart. Hot dogs are cheap, people need a place to congregate, hot dog stands would do that. Most restaurants require payment by credit, or cash, and they are expensive, and after third day would be out of food. I don't think it is possible to run out of hot dogs.

If I did not know it was going to happen, then I would just sit back chill and watch the nuts run by. It is after all only a one week outage.
