I am trying to figure out what I want our bar to include (on a very tight budget). My fiancee and I mostly drink whiskey with soda. We think our guests are mostly beer and whiskey drinkers, with a few vodka and wine drinkers. So I think that Id like to have beer, whiskey, and some sort of sangria signature cocktail, as well as mixers. I am wondering if I need champagne for toasting? Also, should I include vodka and/or wine?
