I'm looking for good cookies in Harvard square. I always end up buying some dry tasteless rusk as a post-lecture snack in the afternoon and want more deliciousness. I like thick (not flat and crunchy like Au Bon Pain's), chewy, and reasonable sized (snack sized, not 500 calorie monsters). All flavors considered. Interesting texture and additions (dried fruit, etc.) are a big plus. I do like Hi-Rise's oatmeal cherry cookie, but, come on, I'm a student and can't afford $2.50 every day.
