The choice of the look of the commercial space we would like to open strictly depends on a simple by essential previous marketing analysis. Very often it's better at this stage to contact an expert company, specialized in design and build of interiors, who will be able to advice you and propose you custom solutions.
Anyway, if you think you can avoid relying on a professional, then you must think about several crucial points.
First of all you must think about the target: who will come into your bar? is you bar addressing to young people or adults? is it addressing to catch the attention of niche customers or do you want that everybody enters?
It's important then to determine which hours are the best: daytime, nighttime or intermediate hours, like morning-afternoon or afternoon-evening, evening-night. So it's very important for you to understand if your cafe will be opened all day long or not, and who is its target.
Then the other step is the place: which is the best place for your coffee bar? Is is better downtown, or at the seaside or in a mountain touristic village? Because, it's clear, the interiors of your cafe must respect and reflect the surroundings. Otherwise you have another choice, which is to opt for a theme cafe, which doesn't care about the place it is located.
These starting steps will help you creating the right mood.
But you can't forget the last but crucial step: your budget. only once you know how much you can spend, you will know if you can open a cafe, or a pub, or a lounge bar or a disco, if it will be an imperial styled cafeteria or a country styled tea room.
Dreams and desires can come true also through careful considerations and study, besides passion, will and fortune.
