I've actually never eaten in the restaurant but, have gotten enough takeout pizza to make some commentary on the quality of that food and the service at the counter when picking it up.
I actually am a fan of the pizza overall but, it's in a change of pace kind of way. I wouldn't put it on any list of best pizza in Charlotte or even on my own personal best of list but, I do find myself craving Prosciutto's pizza about once a quarter. When I order pizza it is almost always topped with pepperoni, ground beef (or meatball) and onions. My favorite thing on the pizza from here is the ground beef. It's actually big hunks of ground beef scattered over the pie vs. those rabbit pellet looking things that show up in the Pizza Hut delivery dudes bag. The crust is not my favorite in that it's not thin enough for me but, it tastes good and crisps up nicely on my pizza stone once i get it home.
From a service perspective, lets just say I hear you to the people who have some less than stellar comments on the dine-in service. Not sure what it is but, most of the folks who have gotten my pizza and taken my cash are just not that friendly.
