At my reception I'll be serving finger foods, so it will all be kind of informal. My venue automatically provides 3 rectangular tables, 5 round ones, and 30 chairs. I'm trying to figure out what to do because I have almost 200 people coming...does that mean I need to rent 170 chairs? What about tables? Does everyone have to sit even though it's informal? Oh, and there are two round benches in the room also. Any help is appreciated!
