So I'm having my reception at a friends house/backyard on the water. I don't want to do a sit down meal so I was thinking of doing light appetizers as the guests arrive and then more substantial food after. Im just so unsure about how to organize it all. Do I get food from a caterer and just set it out for people to get themselves or do I hire some waiters to walk around and serve? How do I make sure everyone has had enough to eat?
