I found King Pizza run-of-the-mill, at best.  The pizza crust on my take-out pie was neither soggy nor burned, though it was a bit tough.  The balance of sauce to cheese was good; but the sauce was the standard-from-a-can sauce one finds in most pizzerias in the area.  Not really worth the trip I made from Tarrytown, looking for a change of pace, but okay if you are starting out in Elmsford.
Pros:  lively pepperoni
Cons:  sparse mushrooms
