Following Vastu Shastra principles in a restaurant helps create a welcoming ambiance, attract more customers, and ensure business success. The entrance of the restaurant should ideally face north, east, or northeast, as these directions are associated with positive energy and prosperity. The kitchen should be located in the southeast corner, linked to the fire element, with the chef facing east while cooking to enhance taste and harmony. Seating arrangements should be placed in the southwest or west direction to create a stable and comfortable atmosphere for diners. The cash counter should be positioned in the north or east, with the cashier facing north to attract financial success. Water elements like a small fountain or aquarium should be placed in the northeast to create a calming effect. Warm colors like yellow, orange, and light brown are ideal for the interior, as they stimulate appetite and create a cozy feel. A clutter-free and well-lit environment enhances positive energy flow, contributing to customer satisfaction and business growth.
