I'm always skeptical of midwest seafood places but Mad Seafood Boiler was really good.
The portions were appropriately sized for the pricing. I had one of the combo boils with shrimp, crab, and crayfish in the cajun spice and it was so savory and delicious. It wasn't quite the same as NOLA, but I wasn't disappointed either.
If you like seafood boils it is worth stopping by!
