Is Burger King open? 
Just pick up and drive through. The one fast food place that I see with a long line outside is Panda Express. Apparently, you can't go into the restaurant because they have it blocked with a table and there's a person who takes your order. I guess you have to be familiar with the menu. Every time I go there I would have to point and say "this one".
I guess people still love their Chinese food. At least none of the money goes to China.
