I grew up in Arlington, half way bewteen Dallas and Ft Worth. Back then Deep Ellum was the hot spot for the under 25 crowd. Lots of great clubs, bars, tattoo shops and so on. That has mostly died out though there are still some good places there to catch a rock show. Ft Worth is actually becoming more popular for night life than Dallas. It is only 30 miles from Dallas. City Streets is a good club there, actually 4 clubs in one building. Take a trip to Reunion Tower, the big lighted ball that you see in all the Dallas skyline pictures. Nice view at the top.
