Boston area recommendations

On Saturday, May 21, Monique and I will be in Boston.  I know many of you will be at LARPs like Isles, The Calling, Volta or Valhalla, but I'm still open to suggestions as to what might be a good way to spend a Saturday night in Boston celebrating a birthday (mine is on May 23rd). 

I'll be going to the 7V IG academic day on the 22nd and Monique is staying in Boston that Monday through Wednesday for a work related function, so we figured we'd go up and do something up there Saturday night.  If you have suggestions for something or can and want to join us, let us know.  We're thinking a show or something like that, but we're not set on anything in particular.
