If you want to look different - then the past fast food restaurant OR any pizza place around you - have your image created (Branded - logo, colors, standards & usage guide, website, marketing material, etc…) and design your decor around that.
We had our location professionally branded and had a designer do the interior when we remodeled and expanded in Jan. '06. We were very happy with the entire outcome - sales rose over 25%. Granted, it is not a cheap way to go, but can pay off big dividends.
We had been operting under the same “look” for 15 years - great product, great service - but same boring look. The rebrand lit the place on fire and brought in all sorts of new customers. If you have the opportunity to start fresh that way, I would definitely do it.
Just my opinion…
