How to watch cheap shows? Here's the trick: show up at 10:00AM at the Copley Square's Bostix kiosk for half-priced Blue Man Group tickets, enjoy the beautiful church and library architecture, then head to the Court House in Cambridge for some healthy, simple and fresh seafood for lunch, then take the Greenline to Boylston and watch the show in Charles Playhouse near Downtown.
I have to be such a prick that I refused to watch any show in Vegas even if they're the same. Hah!
