House of Blues is good (best Jambalaya & Mushroom Pasta), so is Wolfgang Puck's Cafe (Chinese Chicken Salad & Calamari).  Also, you are close enough to SSR, the Turf Club (really good prime rib & lamb chops) is a really nice restaurant with good food and good service!  They are all kids friendly!
We really enjoy the food at T-Rex but I could see how small children might not be comfortable!
