The Jewish holiday Sukkot celebrates the harvest. The Watertown restaurant Branch Line celebrates glorious rotisserie chicken. The two come together Oct. 20 at 7 p.m. for a holiday pop-up presented by the Jewish Arts Collaborative, Kitchen Kibitz, and Ganei Beantown. Tickets include a three-course meal of salad with etrog dressing, family-style roast chicken, seasonal vegetables, and more, plus some festive harvest punch ($75 per person). The patio serves as the sukkah (an outdoor structure traditionally built for the holiday), and a rabbi will be there to explore and explain the rituals of Sukkot. Don’t know what an etrog is? Attend to find out. Branch Line is at 321 Arsenal St., Watertown, 617-420-1900, www.branchlinearsenal.com. For tickets, go to www.jartsboston.org.
