I think the sign says up to an hour. I usually stay longer, but leave if they need the table for others. One time I did get a note on my car, but it was just a warning. If you're in the restaurant for three hours I would let them know which one is your car. If it's crowded, I would leave before that if you're done eating so they can use the table.
As long as you are in the restaurant you are able to park in the parking lot.
