Solid place for a burger and a beer. Since I'm a Chicagoan, Spotted Cow on tap for $4 gives it an automatic 4 stars for me.
Cheese Curds: Less greasy than Old Fashioned's curds. Solid, not memorable.
Burger $6: Quarter pound ("1x1") was well done and juicy. Comes with fried onions and cheddar. I had had cheese curds so a 1x1 was enough for me.
I would go back.
