I am presuming you mean Weight Watchers points? (Sorry I am Slimming World myself).
Try the WW UK website. They do points for some restaurants - although it might be just the usual pizza/takeaway places - but I think I can remember from years ago that they do some basic selections from restaurants. Give it a whirl anyway -

Other than that it might be worth contacting the UK site and asking for any publications they have with restaurant point details.
Sorry I can't be more help!
If you know of a certain restaurant with a favourite meal perhaps you could ask on this board - a UK WWer may be able to help! Give us an idea of what you like to eat.
