It’s only appropriate that the restaurant responsible for producing “alumni chefs” like Lydia Shire, Chris Schlesinger, Frank McClelland, Jimmy Burke, Barbara Lynch and Bob Kinkeade should be a BostonChefs site member. Welcome Harvest. In the hands of executive chef Eric Brennan this Cambridge culinary landmark has virtually guaranteed its position in the top tier of Boston area restaurants with food that’s both rustic and sophisticated. Seasonal tip: be sure to take advantage of the courtyard seating at Harvest during these warm summer months. As good as the food looks, it tastes even better sitting outside.
