Hey hun - is it in the evening? Cos if it was during the day,I was going to suggest going round the Baltic or the Biscuit Factory - always good for conversation starters.
If it is at night, then you could go to the Quaser place in the Metrocentre and leap around a bit hahahah. No? ok - well if you don't like bowling, then go see a scary movie. What about the Departed, the gangster one - that's showing now and it's a boyish film so he'd probably like it.
Or go to the Casino?? I've never been but it sounds pretty swish!
Have fun!
