Friend-of-a-friend is getting married and is stumped over a venue. She and her DP are both pretty low-key, no-fuss, very "green" people and her ideal wedding would be something very simple held in a field or garden (clearly not possible as such, but gives you an idea of what she likes). All the registry offices she's looked at she's found a bit grim and soulless, and she doesn't really want big imposing traditional-style venues either.
Any ideas? I've seen Mumsnet come up trumps on this sort of thing before.
