How do you avoid looking like a generic chain?
The brand is tied to a detail only this venue has: the tile, the neighbourhood name, the crockery or the trade written the way you say it. It looks like a chain when the mark could hang on any street in Spain. Take the name off a proof and show it to someone from the neighbourhood. If they cannot tell which door it is, this place's detail is missing. The palette of a chain the owner saw on a trip gets copied, and the Collado Villalba venue looks like a branch. The regular stops feeling it is theirs.
The mark and the palette come from a photo of this door, and the sheet names that source. The menu shows the same detail, not a franchise pattern.
