Final answer:

The nervous system is responsible for telling your brain that your food has arrived at a restaurant.

When you're at a restaurant and the waiter comes out with your dinner, the nervous system is responsible for telling your brain that your food has arrived. The nervous system is made up of the brain, spinal cord, and nerves, and it is responsible for sending and receiving signals throughout the body. When the food is brought out, the nerves in your body detect the sight and smell of the food, and send signals to your brain, which then processes the information and makes you aware that your food has arrived.

So, the next time you're enjoying a meal at a restaurant, remember to thank your nervous system for letting your brain know that your delicious food has arrived!
