My friend is coming into town for business and will be here one night. She is staying at the Hyatt on Memorial Drive in Cambridge (near the BU Bridge), which makes taking the T pretty impractical (plus, she's very pregnant and may not be up for buses and transfers, etc.). I live in Cambridge and love it dearly, so my first thought was to take her to one of my Cambridge favorites (Garden at the Cellar, EVOO, Emma's, or the bar at Chez Henri). However, she's never been to Boston, so I thought it might be fun to actually take her into town. Any ideas where I could take her in Boston (Back Bay or North End, ideally) that I wouldn't have to pay $30 to park? Or is that too tall of an order (in other words, am I better off giving her the "Cambridge experience" instead?)?
