You might be looking at this wrong. It's not about getting more people through the door. It's about giving them a reason to drive past the other places that are closer.
I've seen this pattern in local businesses before. Most owners go straight for awareness campaigns when really it's a positioning problem. People in neighbouring towns aren't going to sit in traffic for "good food". That's just table stakes. They'll travel for a memory, a story, a weirdly specific craving.
Pick one thing and own it. Doesn't have to be a massive menu overhaul. Maybe it's a Saturday-only pancake stack that looks ridiculous on Instagram. Or a pie that reminds people of their grandmother's kitchen. Something that becomes the reason to come, not just an option.
Also, your existing customers are undervalued. A table tent or a simple card that says "bring a friend who's never been, both get a starter" works better than any billboard in a small town. That referral loop is gold. It's cheap, it's social proof, and it builds a kind of momentum that paid ads can't touch.
And reviews - wait, don't wait. Put a QR code on the receipt, train the staff to ask when people are already happy. Get a critical mass of recent ones. Nothing kills a potential customer's curiosity faster than seeing only six reviews from three years ago.
You don't need more foot traffic. You need a better story for why someone should make the trip.
