Went to a restaurant in Boston called Sibling Rivalry on Tremont Street in the South End. The menu is split with culinary offerings from chefs and brothers, David and Bob Kinkead, who have created a “dueling” menu of different interpretations of seasonal ingredients. I ordered the crispy duck and a lovely beet salad from Bob’s side. Chris ordered salmon and pasta from David’s side. No crossover allowed – it’s one brother or the other. The concept cracked us up, and the food was nice, too.  Loved the dessert cookies. I am saving the coaster for my sister, Seeky.  •
