Selfishly I would open up a Hooters because there is usually only one per city and you'd have a non-stop supply of hot potential talent to catch before they make it to stage 2 of porndom.
Step 1- Waitress at Hooters
Step 2- Waitress at a strip club
Step 3- Stripper
Step 4- Porn
But if I was opening something cutting edge that I thought would do well, it would be one of these, they're hot in Austin and a great concept.
