My 27 year old Washington DC high school teacher son and his wife will be visiting the Boston area in about two weeks. They've been before and had a grand time. They are adverturous and enjoy fine dining, hole in the wall places, local drinking spots and a great outdoor dining and drinking place. Chowhounders' have had great suggestions in the past for this couple and I'm hoping you can come through again. Here's a bit of a challenger: Our daughter in law doesn't eat beef, pork or chicken but she's fine with seafood. Thanks in advance!
