"The most crucial component of any sandwich is balance: of flavors, of textures, of bread to filling," Rob Patronite and Robin Raisfeld write as a preface to their list of New York's 101 best sandwiches. Not to be outdone, Grub Street compiled a list of Chicago's own noteworthy sammies. We found much to love in the workingman's lunchbox, like the meatloaf from Moon's Sandwich Shop and the Italian beef at Al's on Taylor. But several sandwiches reflect our progressive side, too, like the Kogi at Belly Shack or even Sprout's modern grilled cheese.
