Sam's is located in a dilapidated strip mall on the NW corner of Union Hills and 43rd ave. If you see the demolished gas station surrounded by a rental fence on the corner - then you're in the right place.
Hours are a bit frustrating for this place since they don't open until 3 or 4pm and close on both Mondays AND Tuesdays AND holidays. Hope you're not hungry on a Saturday afternoon while watching the big game, or craving Chicago pizza on Memorial Day. And you can't eat your food here since there's no place to eat. Go home.
Crust is thin like many of the thin crust places in Chicago, but it's also quite dry and a bit too cracker-like. They boast the cracker quality, and take it far with the use of that meat tenderizing device to put the perforations in the crust - just like a saltine cracker has. I found no faults with the cheese and sauce, but perhaps I had lofty expectations given their advertising the use of daily made sauce and 100% Wisconsin cheese. I'll give them another shot but may venture elsewhere when I get that thin crust craving.
