How do you avoid looking like a generic chain?
You avoid it if the colour, the type and the photo come from this venue and not from a franchise manual. Do not unify until you look like a branch if the neighbourhood knows you by a detail the chain does not have.

Note what a regular would say to meet: the name, the awning, the bar, not “the chain one”. The green and the type of a big brand are copied and the review treats you as a franchise. You get the mark with that detail of the venue, tested beside a photo of the chain to see they do not match.
