So I bought the 2008-2009 subscription to the NY Philharmonic's program for children.  There are 4 shows.  We attended one yesterday.  It is a big treat for the kids.  We went to the Empire State Building and then to Rosa Mexicano (which we highly recommend) and then over to Lincoln Center for the Paris installment in great composers (the first was NYC!).  The kids absolutely love it and it was a worthwhile investment.  We go back in March and April for the final two shows.
