Depends on what you want to do, if you want a fun cheap dinner and evening....
hit Snuffers (snuffers.com) on Midway in Addison for dinner and beer. It's a burger joint with the best cheese fries in the world! After that you can head over to the Flying Saucer (beerknurd.com) on Montfort. They have every beer in the book.
If you want a more expensive dinner, hit Texas De Brazil on Addison Road. Sambuca is a great place for dinner and live Jazz, it's on Addison Road. But make reservations. Carsons Palace is a fun place on the tollway (if it's still open, their site is all messed up). It should be. There are some other nice place in the Downtown Addison circle if you are looking for a slice of pizza or something. There is tons to do down there.
