I live near Lowell. A friend is staying at the Long Wharf Marriott in Boston next week, and will have a car. I can drive but have a leg injury that means I can't walk easily or manage lots of stairs. We want to meet for an early seafood dinner so I am thinking the Summer Shack on Alewife. Is there somewhere nearby with comfortable seating where we could go afterwards for a long, leisurely chat without feeling pressure to vacate the table? I haven't been to the Alewife area in a long while so I don't know what's there. Something like a Panera would do. No bars, though.
