Well my thoughts were to go to a Chinese restaurant just one junction up from where you are all staying behind the Xscape complex, I have been several times and the food is excellent with a great choice of food to choose from (Chinese, curry, English, seafood etc.). Here is a link to their website to give you some idea, price is £12.90 for the all you can eat buffet which is great value IMHO.

Or there are plenty of other places actually at Xscape and we could even go bowling beforehand for a bit of a laugh.
Happy to organise just need numbers so I can book, also if bowling appeals just need numbers for this too but suggest we get there early evening (6ish) to give us time to have a couple of games and get to the restaurant for about 8. I will put a bit on the end of the 1st post for the evening meal and put everyone down who has expressed interest so far, please let me know if I have got numbers wrong (partners ?) and I will correct.
