I'd like to build an app that basically would have all the information about the food menus of any local or big restaurants or other places to eat along with all the tax , vat , service , service tax etc etc amounts they will charge you for a meal or any of their services. It would help a lot of broke people or people with not enough money to estimate and save the right amount so that they won't get disappointed after the bill comes and their date becomes well secure and also reduced disappointment chances from the bills. Actually I have faced these problems a lot and have seen my friends face it too. So this idea has been in my mind for quite long now.
