We just ordered a pizza and found that there was a strange taste that we couldn't place. It tasted moldy, so we thought it could have moldy provolone, or really strong or old mushrooms. A previous review mentioned their pizza taking on the taste of the cardboard box--that could be it too.
It's too bad. Their pizza used to be great, but we stopped ordering from them after dealing with a rude staff member on the phone (shocking, because it's hard to be rude when someone is just ordering a pizza from you). At least the lady on the phone today was polite and professional.
