Oxford - where is good to go for lunch?

[liveeverysecond]

Stopping in Oxford on our way through on Thursday with 3DDs (12, 10, 8). Can anyone recommend anywhere good to eat and where is good for a wander? Was thinking of westgate shopping centre but wasn't sure if it was walking distance to the centre? Will probably aim to be there was a few hours incl. lunch. TIA

Thank you everyone! We have decided to rearrange due the weather forecast so will bank this for later in august! Thank you - really helpful

If you fancy a longer stroll all the way down the High to Magdalen and the river, you could cross over the roundabout to the Cowley Road and go to Cafe Coco for lunch - it's my old favourite and has a mannequin in a bath so is quirky and fun, plus the food is nice.
