7Bone Burger in Portswood - it's ****ing brilliant and my missus is a vegetarian and still enjoyed it...
For romantic meal Winchester is a better bet - Brasserie Blanc, Hotel du Vin, One La Place (Froggies), The Plough @ Sparsholt, The Running Horse @ Littleton, The Old Vine, Bukkake or whatever the Japanese place is called, Loch Fyne...
