Yep, I miss Wordsworth too. Surprisingly, I also miss Tower Records, on multiple levels - first, because if Newbury Comics didn't have it, they usually did; second, for their quirky appeal-to-Gen-X book selection; and third, for their foot traffic that brought people into the Million Year Picnic.

I miss Cafe of India, which was across Mass Ave from Linnaean Street in Cambridge - my favorite Indian food place.

I was missing the Globe Bookstore in Harvard Square, but they came back! Yay!

I miss the candy & ice cream place that lived briefly just outside Porter Square (down Mass Ave toward Harvard Square). Fantastic milk shakes.

Those are all the ones I can think of right now, with Cafe of India and Wordsworth at the top of my list.
