We've spoken of the corner of Essex and Rivington before. Another great place to pint down, situated on this corner, is The Magician. Although not Imperial, it is still a solid pub that deserves it's due. According to Citysearch, it's named for an Ingmar Bergman film.
Decent jukebox, American 18oz pints, and a healthy selection of beers, all put The Magician on the map. At the very least, they don't stoop to baby pints.
