Trying to find a spot for a rehersal dinner for about 80-100 people. Anyone have thoughts on decent Boston restaurants with either a very large private room or a place that might be willing to rent out the whole restaurant on a Friday night? Desperately trying to avoid the Maggiano's or Legal's options. Would ideally love to do something in the North End or Chinatown (although this second option might be a hard sell with my future mother-in-law). But would love ANY suggestions for casual spots with good food that might be able to accomodate a large party. Thanks!
