Rail ClubWest Loop
Located inside Ogilvie Transportation Center, this dark little bar offers a nice place for a quick one before you hit the train. Or, just grab one to go. They offer cans of beer -- including tall boys -- that Metra usually allows on train (but they've been known to limit the practice during busy nights such as Taste of Chicago). If you're into mixed drinks, you can get them to-go inside Styrofoam cups, as well.
