The food is just bad. You can buy a cheap frozen pizza at the store and get a better tasting one. Burgers are generally dry and nachos are a tasteless mess with canned cheese spread.
If you're with a group don't bother going to the bar for a drink. I was told that I had to wait for my waitress to take my order at my table - that made it 25 minutes for just a beverage. Half price special on drinks only applies to those with alcohol - what if you don't drink. Seems a bit unfair.
Too many other neighborhood places with good food to waste your time at any PT's location.
