Tommy Bahama in Olde Naples is the first restaurant that comes to mind. I always see kids with families there. I can not remember seeing children at Campiello or Handsome Harry's and the menus there are not really kid friendly. Fifth Avenue has some places with kids menus but they generally don't have the atmosphere of TB's. There are wonderful restaurants on Fifth Avenue for adults and I am probably missing one but I know someone will bring it up.
