I am trying to help my mom plan a baby shower for my sister.  We are looking for something not too expensive (hoping to keep it $300 or less) for about 20 people. I am open to location, though something around Boston or Quincy work work best.  I have looked into a few places though everyone seems to have a $500 minimum.  I was thinking a brunch, though really anything that works will be considered!  Does anyone have any ideas to share?  

Thanks!
