I feel like PT's is one of those places where no matter which location you go to, you're most likely getting these three things: an unfriendly bartender, watered down drinks, and low quality food.
What keeps everyone coming back to a PT's are the cheap drinks and mediocre bar food. Here's a tip, though: just stick to the pitchers because the mixed drinks suck. The only good thing about it is that they have happy hour, but it's from Midnight - 2 AM. Come if you don't want to spend your dough on the swankier bars of the strip.
Other than the cheap booze, there's really nothing special about this place.
