The Chicago Italian beef sub ($9.25) at Chicago Italian Beef (1777 Airline, 713-862-2828) is a hoagie roll filled with paper-thin slices of beef and dunked in homemade jus. When the server behind the counter asks if you want it "dipped," meaning with extra jus on the side, say yes. That way you get even more of the tasty gravy to sop up. Make sure you also add giardiniera — pickled, hot Italian peppers — from the condiment counter to your sandwich, which comes with hand-cut, skin-on fries, also good for dipping. Oh, and since the place is normally full of Chicago transplants, it's probably not a good idea to talk about them 'stros.
