I am not a huge fan of pizza to begin with, nor am I by any means a pizza snob or a connoisseur. I really don't give a crap about "true" NY style pizza or what the heck ever. I just know what tastes good and what doesn't...and PMD pizza tastes good.
Their pizza is not overly greasy, they have a wide selection of toppings, the sauce isn't too tangy or too sweet -- in other words, it's not too overpowering and the crust is just right. I usually get their mushroom with ham 8" personal pizza and it is certainly a guilty pleasure. Their cheesy garlic bread is also phenomenal. You get a portion that will last you for days for $6 -- and they are damn good!
If you want true NY pizza go to NY and stop whining :P
