I am having a super casual barbecue rehearsal dinner. The way the drinks work is the venue provides a bartender and unlimited non-alcoholic drinks, and will serve up whatever alcohol we bring in. We will be getting a keg (as the venue does not allow glass beer bottles) and I would like to have a couple of additional mixed drink options for the folks who do not like beer. Margarita machines are not allowed by the venue. My questions:
1.) Any ideas for some mixed drinks that would go well with BBQ?
2.) How many people do you think a keg will serve?
