this now makes so much sense! I have a Hot Box near me and they are the absolute BEST breadsticks since Pizza Express 35 years ago!Pretty sure they aren't the same.
PizzaX is the former Pizza Express.
I think the Hot Box name came to be because they used the Pizza Express name and got sued by the real Pizza Express. I remember seeing it in Broad Ripple and being excited, then realized it wasn't the beloved Pizza Express that got me through a bunch of Sunday nights when living in Teter.
