Restaurant Chain in need of new look

My restaurant has been running successfully for the last 20 years. However, over time new business have moved in all around me. These new business look great and are now starting to my business look outdated. Because of this I am looking for a digital signage services and design company to come in and give my store an overhaul. I think that if I bring them in and create a whole new look, people will remember what it was they loved about us in the first place. All the new stores will fall to second place to the best restaurant on the block.
