I know Winchester well Ria, I go there a lot although I have never been to The Vine. It looks nice though.
Winchester is lovely for a day out. I don't think you will be disappointed
Once you have done the shops and the Cathedral have a wander along the river to St Cross Hospital

Most of the shops are down the high street, start at the top by the old gate and work your way down to the statue of King Alfred
You can't miss him he's hoooooge
