How does one go 7 years without negotiation experience? In any case, my experience suggests that you won't be happy working there, even if they pay you your 70k - it's clear they are after a junior (3 year exp) and value the role commensurate with that. Unless you are getting desperate / it's urgent (in which case you've already lost the negotiation game) I'd recommend looking for a position more in-line with your experience if you want a salary matching your experience - a world-class chef shouldn't expect world-class dollars if he works at a fast-food outlet.
