Our venue will allow us to stay until 3am as long as we have at least 40 or 50 people in the room. I think this is quite likely to happen as most parties, both friends and family, go on until then-ish anyway. So I was thinking it might be nice to have some sort of midnight/going home snack.
Is this something anybody else has done and can recommend or not?
I don't want anything too big or expensive, but most people who will be coming are like me and get the munchies after a long day and drinking, so it would be nice to send them off with something. We're not allowed any outside catering and with people leaving at different times thiings like the crepe vans won't be any good. I doubt our venue will be willing to cook stuff we've brought (ie bacon sarnies) as this would surely come under 'outside catering'. It would also need to be prepared the night before, so does anyone have any ideas? We're having a sweetie buffet as well as a dessert with the meal and lots of scrummy cake, so I don't really want anything too sweet. Or do you think just bagging up some left over sweeties will be fine? Unless we run out
