Whenever we go to dinner with children, my family always goes to Cippolini in Americana Manhasset. It's not usually written up on here, but the food is pretty good. My picky ethnic Mediterranean parents love it, so it has to be good in my opinion. The reason I'm recommending it is because you included your son. It's a loud place so if he's noisy, you won't get at all nervous about it; but, it has an adult vibe.
