Stevelock, I think Fireballs answered you question very well. With limited time it is better to stick to Adelitas or Hongkong for a newbie, you cant go wrong. And what is true TJ experience is subjective, if you are into local Mexican flavor, there are the local type bars like Chavelas, Tropical, nearby to Adelitas. And since you are going before your business/meeting you want to return back minus any incidences so you dont have much of options
