We have tested and tested many variables when it comes to drinks, serving sizes, colors, prices, tastes, and more.  All that a drink program comes down to is taste and appearance.  We give your patrons drinks that include those 2 focal points you can charge whatever you want within reason and keep them coming back!  We have drinks and shots that can be 10% of your total sales and we have tested and confirmed this statement.  $100k annually in one shot that costs cents to make.  The main issue with a drink program is industry laziness!  Bartenders don't want to make drinks that have more than 3 steps and that's where the lack of interest comes from.  The patron comes in and is excited to ask for that 7-step cocktail and the bartender rolls her eyes.  This is a major issue that we run into, needless to say, Patron will not come in again.  You lost another patron.
