My brother inlaw owns a restaurant in town here, i have spoken to him about dogs and restaurants, he told me that, if the health inspector walks in they could get fined, but they worry more about the kitchen and hygiene, so they can't do much about a dog laying next to the owner or in a bag. He is an animal lover, and as long as the dog behaves and is not all over the place they are very welcome. In most places the waitress will serve the dog a dish of water without the owner having to ask for it.
