The Eifel tower is OK, but ..
Its a bit of a walk from London Bridge to get there, you'd be better off having a look around Stratford (just north of West Ham, maps.google.co.uk/maps?q=stratford+london&ie=UTF8&split=0&gl=uk&ei=JNgVSomDL-CrjAf524X8DA&t=h&z=12&iwloc=A) which is famous for being Shakespears birthplace and has a variety of related exhibits such as Anne Hathaways cottage.
