Server-Server #waiter

• Pain points
• To customer: You go to a restaurant and order something the first time. Then afterwards, for ordering the next item (which will typically be extra naans or some new thing). But calling the waiter: "hey bhaiyya"/"waiter" or some other thing is a problem. Even bigger problem is when you don't remember who your table's waiter is - and you want some spoon/onion or something.
• To customer: You don't know how each item looks in the menu. Typically you ask the waiter about specific items: "Bagara baigan mein gravy hota hai kya?" kind of questions. The pain here is that the number of questions you can ask the waiter is limited (you can imagine why) and you cannot see how every item looks like.
• Also, if there are some suggestions about what is special/quickly available/generally preferred item in a particular restaurant, it will be helpful to the customer and the restaurant owner will be happy to provide this data for the users.
• Idea
• What if all the menu cards/restaurant tables have QR code or some marker? When customers arrive at the restaurant table, they can point their smartphone cameras to the marker, which fires the menu up. The menu will be a standard card type menu, where items are clickable. 
• On clicking a particular menu item, you can see the image of how it looks like (solves the gravy problem), quantity information (veg biryani in different restaurants serves different number of people), etc.
• When you want to order another item from the middle of your meal, you order it from the app itself (you give the quantity and item), you know the running price (track to see if it is in your budget), you get suggestions about what is popular in this restaurant, etc. Basically, computer server becomes the hotel server here...
• What more? The order you give fires up a timer, if you do not get service within a time, you can rate the restaurant directly from there (think improved service).
• Once we get all the rating/orders/popular-items-in-a-restaurant, etc. we can provide analytics about it to the restaurant owner about what items are going well, what needs to be improved, how is the service at each table, etc.
• Since we know all the analytics, we can provide discounts to repeated customers (configurable by the restaurant owner).
• Technology challenges/description
• The augmentation part is easy.
• Analyzing the data and giving useful feedback to restaurant owners is a big data/text mining challenge.
• Marketing this app to users and restaurants.
• Competitors
• Yelp/OpenTable (not direct competition though), FourSquare (in the discounts category).
• Market 
• All restaurants which expect customers who have smartphones with cameras.
• Business model 
• The app can be free both to restaurant owners and customers but the data of which item is being ordered by whom, and how many times (data analytics/market research, basically) can be sold to other companies or even restaurant owners themselves.
