Conduct a survey regarding the likes and dislikes of your customers. You can ask the customers to fill out a questioner or just monitor the orders that are placed, as this will give you a clear idea about the items that need to be added in the menu.
Items which can be served quickly should be included in the menu to accommodate customers looking for a quick fix.
Before finalising the menu, you need to prepare a cost analysis regarding the ingredients needed to make most of the items in the new menu.
Always test several batches of new menu items to ensure quality and taste. When a new item is tested by the staff, take input to improve that particular item. You can also adjust the price according to employee feedback.
Menu items which are unpopular, hard to prepare and expensive, should be replaced with better options if possible. This will bring a rapid increase in sales and customers.
It is always better to have a menu board clearly visible for the convenience of your customers. Post information regarding your new offerings. Picture displays will tempt the customers to actually tryout the item. You should clearly mention the price and nutritional information of all the items being offered in your restaurant.
New items require proper promotion; you need to get the word out for people to know what you are offering. Make posters of the items and display them on the walls and doors of the restaurant. Keeping the capital you have for promotional purposes in mind, it is advised that you use billboard, radio or television advertisements for promoting your products.
