ChiBBQKing told me that Marko’s Fish House in Madison, Illinois served one of the best fish sandwiches.
I had to see for myself.
Madison, Illinois is a smaller city of approximately 5,400 residents located just across the river near Granite City. Until this day, I had visited neither.
The first two things you should know before heading to Marko’s is that its open Tuesday-Friday and that you need to bring cash.
