Short version of what's gettable on a restaurant, roughly how we get it, and how deep you'd want us to go. Tell us which parts matter and we'll build to that.

Same five steps whichever campaign it is. Only step 1 changes.
Why step 4 matters more than it sounds. On the Arizona sample we found a candidate name for roughly 8 in 10 restaurants and kept 7. The ones we dropped came from customer reviews, which is where a reviewer's own name gets mistaken for the owner. A caller asking for the wrong person has burned that account. A blank hasn't.
Three levels. They stack, so you can start light and add later.
Business, phone, website, current POS, size, plus a verified owner or GM where the open web names one. This is what's in the sample files.
Pull state business registries and licence records so the owner comes from a legal filing rather than an article. Much higher coverage, and it's the difference between "we found a name" and "this is the registered owner." Free in a good number of states.
Inspection dates, licence renewals and hiring activity, so your team calls when something just changed rather than at random. Plus direct-dial enrichment where it's available and you're comfortable with it.
Independent restaurant owners barely exist in the databases most vendors resell. It's doable through other routes, but there are rules around calling mobiles, so it's worth a conversation rather than an assumption.
POS leaves a public trace. Who does their payroll or card processing generally doesn't. We can get at it in some cases, but not as a reliable column across a whole list.
