flying fish, citricos, california grill, or narcoossee's. your meal at california grill can tends to be a little bit slower pace so if your child can't handle a really long meal the others are great choices that go a little quicker. flying fish has the advantage of being on the boardwalk. we've come straight from dhs and felt perfectly comfortable going into flying fish in our park clothes.
last december we went to california grill, we had on business casual but my sister and i were both really cold so we grabbed our mickey mouse sweat shirts out of the car and wore them over top (just had to we were just that cold and yes were fashion road kill) and no one batted an eye...they sat us, fed us, and happily took our money.
