My sister turns 40 next month and all the family (8 adults, 5 children 4-11) are off to London for a few days to celebrate. We want to book a nice lunch somewhere on the Saturday, but need to make sure it’s family friendly, cos of all the children! We really don’t want a themed/ children centred restaurant, more a ‘naice’ restaurant that would be fine to take well behaved (I hope!) kids to. Any ideas? Thanks!
