I always cringe when I see someone go into Domino's here in Chicago,WHAT ARE THEY THINKING!!!,maybe they are trying to save a few bucks at the expense of taste.
The worst pizza I can recently remember having was a place in Park City Utah.The Red Banjo Pizza parlour.
I remeber walking in and seeing almost no one there(a bad sign) and the place looks like an old saloon(another sign?)
I got a slice of pizza that was TERRIBLE.I had to force myself to try and eat it,but I ended up throwing most of it away.and I was starving,which usually makes not so good food,good.
Funny thing is they had a sign saying "voted best pizza in Park City"
here's a link.
