I really don't know much about DD. A friend recommended Fulton's Crab House, while another recommended T-Rex or the Rainforest Cafe. Someone else mentioned Raglan Road. The one time we were there we ate at Wolfgang Puck Express, which was very good.
Ideally, I'd like to make reservations at a child friendly place with good food that isn't outrageously expensive. Is that too much to ask? Probably.
