Ask HN: How do I get customers/users?

I have a marketplace company, (here’s a listing - https://tinyurl.com/j7atzhb) that connects people that are looking to dine-out at great restaurants for great value, by allowing them to book value packages in advanced.

We have 10 live listings with value packages up to 35% off, how do we market them to get bookings?

The owners of the restaurants want to see results, and I'm looking for actionable tactics on how to get users/people booking these packages.
