Not sure about the "decent night life" part but for a family dinner with great food and atmosphere I recommend Grand Lux Cafe at the Galleria. It's lush but casual and the food is amazing. It's grander than Cheesecake Factory (done by the same guy) but it's their next level up, the food is tons better and is a great place to take out-of-towners.
I also recommend Maggiano's, it's roomy and you can do family style dining (easier for everyone involved).
