When going to the beach for the day most families take sandwiches along. It's pretty expensive for mom and dad to treat the family to lunch at a beach-side restaurant - especially when the kids NEED to be at the sea every day. :)
Kerry-Anne and I don't have kids so we most often have lunch at the closest restaurant that takes our fancy. Now, I guess for the sake of family peace I have to admit that we have two feline children, William and Elizabeth. But, William's in the dog-box at the moment... he pushed the Christmas tree over in the middle of the night. grrrr....
