For a restaurant where you see all age groups:
MB
AFM
MM
Back to LCD :
I would say SW but too complex and most folks would be turn off by its depth but it’s a universal theme it would grab attention.
Munsters is easy enough to grasp off the fly
and good for someone to sink into with its overall campy, comedy, horror theme.
Finally, DP might fit in good but something about the late 90’s SS above would be ideal.
Still with the dots but overall the themes you can’t beat.
Oh I think Wonka down the road would be good in this atmosphere.
