If what Zella's makes is pizza and breadsticks then MacDonalds is a Michelin star restaurant. Pizza has a terrible crust and their breadsticks are more like tortillas than breadsticks.
Based on what I received I will never try Zella's again. Pizza Hut is better. And Pizza Hut has never made anything that resembles a real pizza in its life.
The person on the phone was anything but cordial and welcoming. If this were my company, I would fire him immediatley.
Zella's will not be around for long, unless they get help from Restaurant Impossible. Based on reading other reviews, Zella's is either very inconsistant or perhaps some buyers are not aware of what good pizza should be.
