If you saved your holiday shopping until the last minute (ok, maybe not quite the last minute, but definitely the last week), then mark your calendar for Sunday, December 16th. The folks from Choix and Gladstone Jewelry are coming to town — it’s not quite time for Santa, yet — and they’re popping up in Cambridge at Pammy’s. From 11:00am to 3:00pm, peruse unique homewares and unusual bling from the two visiting vendors while sipping on mimosas and eating light bites from chef Chris Willis & kitchen crew. No need to RSVP; just swing by 928 Massachusetts Avenue.
