Those pictures are fantastic and seeing them here really makes me miss Marty's, though I've only ever eaten at the one in Delafield. Every time I had to drive past that town, I made sure I planned to stop for a meal. I'm not sure whether it's the case at the one in Brookfield, but the Delafield has an all-you-can-eat option where they bake pizzas to order and keep bringing them out until everybody who's getting the all-you-can-eat option has had enough. I'm pretty sure they'll box up the leftovers for you if you do that, but it's been a long time since I've gotten anything other than just a small or a medium (I usually was driving alone when I went through Delafield). That said, there is another two-location "chain" in the Milwaukee area that has similar pizza: Balistreri's. I don't have enough posts here to post an actual link, but there's some info on them at balistreris.com for anybody else passing through the area. I've heard that they used to be Marty's locations, but I'm not sure whether that's true or not. Either way, both Marty's and Balistreri's have delicious pizza and I really miss both of them.
One place that I would recommend trying if you're ever back in Milwaukee, though, is Pizza Shuttle on N. Farwell Ave. It's just a bit north of downtown and parking can be a bit of a pain since the city sold off the lot next door to build apartments, but it was my favorite pizza shop during the 8 or so years I lived in Milwaukee. Some of their food isn't quite as good any more (I think they changed to pre-formed crusts for the thick crust round pizzas and they're cooking the breadsticks a bit differently, for example), but just before I moved out of the area in late 2007, I had one of their square Sicilian pizzas and it was just as good as ever. I'd suggest the Sicilian there, but the regular crust round pizzas are good, too. There are a couple of downsides, though. Their pizza is extremely heavy, so it's not something to get if you're in the mood for something light and it's usually better when eaten at the restaurant, but it's well worth it. Again, I can't post a direct link to their site, but they have their full menu, location info, etc. up at pizzashuttle.com.
Anyway, thanks for the awesome reviews. I really enjoyed them. 
First, thank you, too, and I'm glad you enjoyed the photos.
Second, I have heard of Pizza Shuttle in that part of the country. I am hoping it is not any relation to the Pizza Shuttle that opened up in Lawrence, KS in the 1980's as I was going to college there. It is still there and still going strong.
http://www.8421212.com/Basically, it has always been known for cheap, fast pizza, but never good. I think I might have tried a bite of one once. That was enough for me. For college guys drunk out of their minds on brew and purple passion, it (or anything) will fit the bill, but for me, I guess I can only lower my standards so far. I think the Pizza Shuttle in Milwaukee is probably a different animal, which is a good thing. There were a couple of other places in the Milwaukee area I would have liked to have tried, including Maria's Place on West Forest Home Avenue and Zaffiro's. Maybe next time.
