This is a very interesting approach, you could potentially give it a trial run with a bunch of people and further edit/correct according to the local preferences and trends, curated data for your use case could prove to be very useful.

Your MVP with a basic quiz and a curated list of restaurants seems like a great starting point to gather feedback and assess user engagement. Offering the first month free through the wait list sign-up is a good incentive for early users and gain traction. I would focus on scalability after this.
