For more than 60 years, Joe Boston has been serving Chicago beef, and damned if he's changed thinking about changing a thing. The sparseness of the decorations on the walls are matched only by their age. The sign outside is equally ancient, and stands as an island lost in time. The continental might only be two blocks east, but stepping into the dim interior of this no-frills joint, one finds time lost in a classic (but thankfully not "retro") environment that only seems to enhance the sense that you're eating something lost to the modern world.
