My preferred place to study for school or exams - tables are good size (one in particular can fit two people, but I like to grab it for myself since my books and papers need to be spread across a larger table). Outdoor seating is nice and overlooks the start of the greenway.
Small, but intimate seating - I've seen book clubs meet here, lots of grade school aged students with tutors, professionals with laptops, or the casual coffee junkie.
