Will need restaurant dinner rec for about 12-15 people for Thurs May 28. Graduation is in Cambridge (Harvard) and we are staying at the Boston Park Plaza. Looking for wide variety, one member is gluten-free, one wants steak/prime rib, could be Italian, French, American. Tablecloth dining and reservation required. We are out of town. Want a memorable experience. Graduate doesn't know from $$$ restaurants. Thanks!
