Area Four in Kendall Square feels kind of like a cafeteria, except it has pizza and beer flights instead of overdone burgers and chocolate milk. That’s an improvement in and of itself, but in this case the pizza has perfectly crisped crusts and toppings from one of the best delis in Boston (Moody’s in Waltham) and flights of craft beer. You should start with the bacon and clam pizza, but you probably already knew that.
