Restaurant interior design is more than just the visually pleasing effect it has on it's guests, it should also be a part of your overall theme. Interior design sets a mood, sets the ambiance and interior design can also play a part in your table turnover if you're in the QSR business. Corporations spend a lot of time and money creating their image, their corporate colours and their interior design. Often, a business will identify itself with colours and branding specific to their message. Look at Starbucks. Masters of blending into a neighbourhood, designing themselves into a culture of coffee and locality. So, it's not just tables and chairs, it's a look that you should give some serious thought to.
