The Conferencing Facilities at the Holiday Inn Royal Victoria in Sheffield was quite a nice venue when I was on a one day training course there.
The facilities were quite good, with food and drink available as well as free parking. The location was reasonably close to the centre of Sheffield, so would be good for anyone travelling by train.
The only niggle was the limited multi-media facilities - our conference presenters had apparently brought their own projectors and screens, though I got the feeling that the venue was more "meeting" than "presentation" oriented.
