How wonderful that you are visiting Walt Disney World on Valentine's Day!  There is no better place to be than Disney on any Holiday.  I have a few suggestions for you for restaurants that will please both the adults and the kids in Downtown Disney.  My family just loves T-Rex, A Prehistoric Family Adventure.  I think the food is wonderful, and your kids will love all the theming.  I would request eating in the ice cave.  On the West Side, I would suggest the House of Blues.  This is a great restaurant, and the Lobster Macaroni and cheese will change your world- it is THAT amazing!    Lastly, if you like menus inspired by South and Central America, Paradiso 37 is the restaurant to visit.    The Central American Crazy Corn is delicious!  They have a great kids menu as well.  I know whatever your choice will be, your Valentine's Day celebration with your family will be just magical!
