I'm going to jump in and ask why if you're doing well with Facebook you're moving to search here? I have to say my feeling is you're not actually going to get a lot of bottom of funnel traffic - people don't really google for a coffe shop before visiting one, whereas the right video ad at the right time . this looks like a rare example of "more YT, FB and Display proably for this niche", but that's not from direct experience.
