We didn't do Dick's Last Resort on our last trip because we weren't sure our little ones (mine and my sisters, all under 6) would be ok with it.
Ryan's Steakhouse, it's a chain, is good for family dinners. If you just get the 'buffet' you'll have tons of food, the kids will have lots of choices and a great dessert bar (my son LOVED this) and the most awesome, yummy yeast rolls in the universe. It's not a fancy place by any means, and not at all gourmet, but our crowd was happy with it.
We also had several meals at Sonic. Don't laugh, there are NO Sonics in our home state of CT so this was a BIG treat! LOL
And I believe there's a Five Guys down there now too, they have GREAT burgers!
River City Cafe at Barefoot Landing was also fun with the kids.
(BTW, for anyone with peanut allergies Five Guys and River City are NOT for you.)
