Ha, thanks! I have slowly been learning that if we set out our expectations clearly before we go into these things, they usually behave quite a bit better than if we don't explain what's happening beforehand. So we said that we were going to a posh restaurant, there would be no phones, they had to sit down nicely and they would only be able to order dessert if they had behaved during the meal. This appears to have been sufficient motivation! :P
