All the wheels are in motion. Time to figure out a budget. It is hard to build a budget without a design. Talk with your Architects and Designers and target a square footage charge. In the meantime while they are working on plans research cost associated with Permits, Plans, POS Systems, Audio/Video, Security/Cameras, Kitchen Equipment, Small wares, Tableware, Glassware , Advertising/Public Relations, Employee training, opening inventories . There are many other areas of cost. This is really a great time to start comparing and pricing all of theses services. There are good companies that specialize in the Hospitality business and understand your needs clearly. I suggest you work with them.
