I have traveled to Cambridge a few times this fall and ended up at Crema Cafe each time. The first time I went, it was just for drinks with friends. I ordered a warm lemon-ginger drink and was hooked. It is amazing! I have returned on each subsequent visit to enjoy the lemon-ginger drink, as well as some of their food, all of which has been good as well. Although the line can be long, it moves quickly. To get a table, you may want to get there a bit before you plan to sit, if you are going at a peak time (e.g., weekend mornings).
