Mex. City was amazing at that time.  Really easy to walk down the street in tourist areas and find amazing clubs where the girls would sit with you when you buy them a drink and try to get you to take them off site for an hour or so (I twice had all-nighters at no extra cost).  These girls were very often amazingly good looking; GFE was possible (altho in those days that term did not exist as far as I know).  I even had one girl later visit me in LA - she got in on a tourist visa and stayed a month or so.

The only trouble I had was getting a girl into my hotel room on one occasion - apparently, the hotel was accustomed to mongers and didn't like it, so if they saw a gringo with a hot chica they tried to stop it by seeing if she was registered before letting her up...I can't remember anymore how I did it, but I got pretty good at finding a way around this.

The bottom line: in those days, at least, it was easy to find bars like I am describing.  The ones I found were near Zona Rosa.  Didn't need a computer, just needed to walk down the streets where the places were located...as always, Spanish helped a lot.

Good luck!

btw, Mex. City has amazing art...really among the best cities for art in all of the Americas.  Chapultapec Park is incredible...you might wanna make sure you take enough time off from mongering to go see it!
