Gigio's brings back memories of graduate school. Slice of sausage, slice of cheese, can of diet coke. But it's really, really greasy pizza, the kind that you need to blot before eating.
Two Brothers is Elmhurst does a very nice thin and reasonably inexpensive crust, good enough to get me away from stuffed pizza for the six years that I lived there.
I am not a fan of Malnatti's at all. Ditto with Home Run Inn - they're four blocks from my house and I ordered from there the day I closed on the place because I had a bunch of relatives over to gawk at the empty place. Never again - it was like eating saltines with no taste.
