Mom & Pop Restaurant recommendations

I’m going to be visiting Milwaukee next month for a two week stay and I’m trying to find some good places to eat near downtown.

Im not looking for fancy, crazy expensive or those places that are trying too hard to be hip. I’m a blue collar dude who loves burgers and beer and I’m trying to eat my way through the city. I’m talking local favorites you’d take a visiting buddy to.

Also, I’m trying to get on this cheese curd train since we don’t have anything like that in my area. Is there a best place to get them? Are there different types I should try or are they just curds and get them everywhere.
