Part of my job is to spot places that need help. Since many business owners have no sense of design, it is my responsibility to be able to communicate my ideas to them in a way that is easy to understand what I am seeing.
Most people know what looks better if they can see a before and after, but perhaps wouldn't have thought of the idea that I'm presenting to them. By doing this, I can shine a light on something that the owners may not realize they needed, then, granted that there is enough budget to work with, we can take their place to the next level.
After analyzing the business concept, I usually develop ad hoc visuals that go with the theme, then I photoshop renderings of different options that would vary dependent on the budget. This restaurant's theme is 'black panthers' and it is a Mexican restaurant. The restaurant is beautifully set up, with brand new everything and exposed brick (which New Yorkers LOVE), and it just needs a little push to take it to the next level.
There are some more design recommendations I would make to this business, however I usually like to build upon the changes in order to make everything work best.
