I'll let timber do the scouting.
Put it this way -- fishfries are a WISCONSIN tradition, but Madison is both of and separate from Wisconsin.* They have 'em, but it's not really a Madison thing. Madison is more weird, non-traditional, eclectic, ethnic type stuff.
*I have a friend who does a stand-up routine, talking about growing up in a town outside of Milwaukee. It's hilarious, but I commented to her afterwards that it didn't seem like Wisconsin to me. She said, "Honey, you've never lived in Wisconsin." I said, "What are you talking about?? I lived in Madison for 8 years!" "That ain't Wisconsin."
