As long as your children are "restaurant friendly" (able to sit for a longish dinner, not yelling, screaming, crying, not running around or hitting/kicking the other patrons) you will be fine. Narcoosees has a children's menu and many families will be eating there, even at 7:30. However, please be polite and don't let your children ruin the dinner of others if they are unable to behave in an appropriate manner
