Chef Rachel Klein offers Harvard Square theater goers, whether they’re ART bound or just heading to a movie, a three-course prix fixe menu that’ll make sure you’re well fed and comfortably in your seat by the time the lights go down. Available from 5:00-6:00pm, the pre-theater prix fixe costs $40 per person (or $50 with accompanying wine), not including tax or gratuity. Some options from the menu: corn soup with bacon, vine ripe tomato and cilantro; apple cider-glazed pork with savoy cabbage, white grapes, sour cream and chive crushed potato; and chocolate tart with Lady Grey ice cream with bergamot mint syrup.
