I love trying new (old) pizza joints. That being said, I live on the North Shore, so I've had very few of the south side and south suburban pizzas. I've had Villa Nova a bunch of times, but only from the one in New Buffalo, so I can't comment on the original location. The New Buffalo location is very good for this style of pizza. Even better when it's in Michigan and your options are slim.
I tried pizza at Michael Salerno's pizza in Glenview, but is it related to the Salerno's Pizza on Grove in Berwyn? The one in Glenview was simply awful in every way. I normally will give a place the benefit of the doubt if there is something that can be tweaked (extra sauce, well done, bad night), but there wasn't a single thing about this place I could tweak to make it better for me.
