Show it to the barman in a noisy bar or show it to your friends so they know what to get you.
NB - after some communication from users, it is necessary to point this out - this app is _just_ a tool to decide which drink to, well, drink. The app was created in a few minutes as a hobby project between other jobs, so it is not feature rich, its price of 0 dollars and 0 cents is intended to reflect this. We all have moments of indecisiveness, and this app is designed to help alleviate the sting of those moments, so other people at the bar who know what they want can make their order faster so they can get back to working on other things...
It will not make your drink for you, it will not tell the bartender how to make the drink (any bartender worth their salt will know how to make these drinks, and many more, without any reference tools whatsoever), it will not pay for your drink (really not sure what that user was expecting), and it will not drive you home (again, not sure what that user was expecting but I doubt they will achieve it without many years of research, the use of robotics and a suitably fast interface between their car and their phone).
