We ordered Isa's 18" pizza with two toppings for pick-up. When we got it home, I grabbed for a slice, put it on my plate, and found my fingertips black with soot. I put the pizza back in the box and immediately returned it for a full refund.
Our pizza looked as though it was dragged along the bottom of a dirty fireplace. Isa's isn't the only Phoenix pizzeria guilty of this, but this is the worst instance of a sooty bottomed pizza I've had in Phoenix.
The 2nd star is for the staff, who very efficiently and apologetically handled our refund. However, despite the staff's handling of the situation, I strongly urge you to consider a different pizzeria.
