I like the open atmosphere and layout of Open Book. This is a good place to get a cup of tea, read a book or consider making one of your own (in the book arts center a few feet away).
When I went they had one vegan soup (artichoke) and some vegan rice crispie bars from French Meadow, but no vegan sandwiches. Unfortunately, they only carry Oregon Chai, which is a serious negative point, in my opinion.
If they had some vegan cookies or cupcakes, along with a tofu or tempeh sandwich, this place would merit an extra star. As it stands, it's pretty decent.
