Hi Everyone- I need some help once again 
We are having an open bar and therefore i did not order additional champagne per person because i figured everyone could just have what they wanted. We are having 65 guests and i know a majority of people wouldn't drink it. However, some guests may be looking for it. Is it possible to have it available at the bar to order a glass if you would like it rather than put it on the table for everyone?
