My family and I have been going to Knoebels since I was a like 1 or something... We go up every summer to continue the tradition with my daughter. I actually remember Knoebels without Cesari's...
I often stated that this pie was the best I had ever tasted, and I'd still go with that especially in the late 90's / early 2000's... My brother and I have noted that the past couple years the pizza has changed slightly though we can't put our finger on it... they do have a number of kids back there making pies so perhaps its a human factor, though my cousin believes they have changed the recipe.
Cesari's produces a number of pizza-like offerings including some Sicilian and calzones... but stick with the plain / classic marguerita and you will enjoy... the dough is crisp, but chewy, the sauce is memorable, and the cheese is great.
Highly recommended even though it may have slipped a notch or two on my list in the past couple years.
