It's either Downtown Fort Worth or Downtown Dallas...they are pretty much in opposite directions of each other
If you are going to downtown fort worth then yo are going to be hanging around mostly white people and hispanics....the spot to be is going to be downtown...every place downtown is going to be full of people...probably super drunk white people and hispanics, but people nevertheless...
If you are going to downtown dallas you are going to have a mixture of every type of person on fri sat sun....wherever you go you want to check if their is a theme for that night....some places only have hip hop on certain nights, or they have spanish night on certain nights...typical club shyt...anything around Main or Elm street should be popping...You will also be closer to strip clubs, though the best ones are not downtown...they going to be farther up I35 around the 114 exit (Spearmint Rhino , Onxy, Black Orchid)...Black Orchid can be
or
...
I can't imagine taking a cab from either one of the places out to the stadium...I have no idea where cabs even drop people off at...I been to plenty of games over the years and I can't even remember the last time I saw a cab drop somebody off remotely close to the stadium... it's pretty far from both places so catching one is going to cost quite a bit
Park Ave is cool. I think Saturday is hip hop night. Any other night I think is "grown up" night. In the past they have been known to trip about a dress code so you want to wear at least a button up and shave halfway decent.
