Thanksgiving Eve is one of the most popular drinking nights in America, and on Wednesday, November 21st, Branch Line in Watertown is making a case for staying local. They’re transforming their heated, enclosed patio into a Bavarian beer hall, complete with off-menu specials of German-style brews, beers by the pitcher and schnitzely, sausagey snacks from the kitchen. No tickets, no reservations, no cheek-pinching aunts, just get there and fill up before the long meal ahead. Call 617.420.1900 for more info or just pop on over to Watertown after 4:30pm or so.
