If you park in back, feed your meter, even if you are there late at night on a weekend! Other than that, Kayak's has great coffee ("kick in the face") and a fun "outdoor" atmosphere. It is like a ski lodge. They do have loose teas (bonus!) and of course, tabletop smores! What could be better? Oh, some of the locations serve alcohol too. It can get a bit cosy during the school months since WashU is on the opposite corner, but it is still pretty big. They also have sandwiches and salads, but not a lot of baked goods.
