Grafton Street Pub & Grill celebrates 20 years of serving Harvard Square with their very own specialty beer. Stop in on Tuesday, October 25th from 9:00pm on to raise a glass (or several) to two decades of restaurantry. There’ll be small bites and specialty cocktails, and Harpoon is helping the festivities with an exclusive beer for the occasion: the Crimson Kolsch. Grafton will pay the good cheer forward donating the bar proceeds from the night to St. Francis House, the largest shelter in Massachusetts. The Kolsch will be on tap at all Grafton Group properties (Grafton Street Pub & Grill, Temple Bar, Park Restaurant & Bar, Russell House Tavern, The Hourly Oyster House and State Street Provisions) as long as it lasts so swing by to raise a glass. Call 617.497.0400 for more information.
