From now through Sunday, August 6th, Harvard Square businesses get a pinkish hue as part of a Square-wide Breast Cancer Awareness Campaign, Think Pink, Drink Pink and Shop Pink. Stop by the Carriage House Salon for a pink mani or pedi, pick up a copy of The Best Women’s Travel Writing of 2006 at the Harvard Bookstore or have a cocktail at any number of area eateries and a portion of the proceeds will be donated to either the Alice Hoffman Breast Center at Mt. Auburn Hospital or the Susan G. Komen Foundation. So, head to the Square for a raspberry lemontini at Rialto, a glass of Beaumont des Crayeres at UpStairs on the Square or, depending on what’s in season, a raspberry or strawberry lemonade at Henrietta’s Table. Check out the Harvard Square Business Association’s website for a full list of participating restaurants and the full rundown on the Think Pink promotion.
