We love Hennessey's.  Been to several in SoCal.  I was really looking forward to lunch there.  Our beer order was taken within minutes.  A different waitress introduced herself and confirmed our order about five minutes after that but she had the order backwards.  A few minutes later our drinks were poured and set up at the waiters station to be delivered.  That's as far as the got.  We watched our beers get warm and flat for easily ten minutes and no one brought them to us.  I felt that we became invisible.  Our food order was never taken.  We saw another couple sit and leave because no one even talked to them.  The restaurant was not crowded and there were several employees there. Our drinks didn't come so we left.
