How much does it cost? Do you do walk in or do you need appt?

Yeah, what he said. Honestly, I don't understand why people think they can get the answers from "GOOGLE F'IN MAPS" before trying the actual website or even, dare I say, calling the company or service in question! Google maps is a tool to help you find something or somewhere, not specifics about said company. Look it up! It's so damn easy!

Yes, appointment to drive, can walk in to eat and look around

It's best to have an appointment as the luncheon area is that large, it is a wonderful experience to over look the car race track while dinning

Prices vary dramatically for what your interested in. Check the website, appointments aren't required but different dates have different packages. https://www.porschedriving.com/home
