In the Venn diagram of cereal and cioppino, Glenn’s Diner is a perfect circle. One of the most adorably unusual seafood spots in Chicago, the casual diner has the look and feel of a roadside stopover for pancakes, French toast, and omelets—but it just so happens to also have a seafood focus and an abundance of fresh fish at affordable prices. This means you can have your cake and eat it too. Or in this case, have your cereal (the restaurant has dozens of nostalgic varieties lining the shelves like trophies) and eat a cornmeal-battered shrimp po’ boy too. With so much variety—from hollandaise-slathered catfish plates and cioppino to crab cake “burgers” and lobster fettuccine alfredo—Glenn’s is one place where classic comforts take many forms.
