On a recent visit to Eastbourne I stayed at this b&b thinking that it was going to cater well for vegans and vegetarians.
The owners were very friendly and lovely, made me feel welcome, however I think that they should improve the selection of breakfast items and make it more veg-orientated and serve things that aren't served in other b&bs. There was bread, jams, croissants, cheese, yoghurts, muesli plus some soya yoghurts for the vegans. However, you can get this kind of breakfast in any b&b (minus the soya yoghurts.) There was no cooked veg*n breakfast which is what I would have expected as something you don't normally get in other places. If they really want to stand out as a vegetarian b&b that's what they should go for, yes the owners are lovely and the rooms are nice and reasonably priced, but if you choose to be catered for as a vegetarian or vegan you would expect more.
I would go and stay there again for how I was treated and made feel welcome, but there wasn't anything particularly vegetarian or vegan that you couldn't have got elsewhere.
Cons: you could get their breakfast elsewhere, cold room, no extra blankets in room
