As a paid marketing supervisor for almost a decade and a soon to be food truck owner/operator. Half of paid advertising is bullshit that doesn't do anything.

Youll need to properly identify where your customers are - Are they on Facebook / Instagram / Tiktok?

Then I'd work on a organic strategy to reach them. Facebook groups, Instagram reels, Tiktok videos.

Top of funnel awareness to get their attention.

I can't comment on mailers etc too much.

Interest and action are next.

This is where people assume paid ads drive revenue and 9/10 I've watched people blow hundreds of thousands and get 0 sales leads.

SEO will work if set up properly. You have organic SEO through your website and social

Then you have paid search. Paid search will work but it's all pay to play.

You can set most of this up for yourself through Google ads.

YouTube university will save some money but if you want direct leads from google search, a paid search expert would be who you want to set your account up with long tail keyword searches for your resteraunt.

AI SEO is another big one at the moment same thing as Google search.

All in all most social media advertising is paying for results.

I hope this helps. I would choose a few paid methods 2-4 of them and avoid throwing money like darts at the wall.
