Chef/owner Joanne Chang is a Boston superstar, known for her small chain of high-end bakeries. (She’s also the Chang in Myers + Chang.) Flour’s sticky buns, made with caramel and pecan, are justifiably renowned, and its decadent sandwiches, salads, and grain bowls are also first-rate. There are also locations downtown and in Harvard Square. If it’s is too crowded here, head to Sweetgreen around the corner at 372 Congress St., for a fancy salad to go.
