We are serving heavy apps for dinner, will have cake and a little bit of pie (not nearly enough for everyone, it's in lieu of the groom's cake). So a little later in the evening we are having a s'mores bar. Right now my count is right at 100 people give or take a few. So do I tell the caterer to do it for all 100? there will be less than 10 kids there and I know not everyone will have one. So, any ideas or suggestions on what my number should be? Caterer was just like "whatever you want" lol.
