Webster's is wonderful. It's has a chill, friendly atmosphere, soy milk and almond milk options for drinks (such as tea lattes), and a variety of vegan entrees and desserts. Not to mention it's a bookstore that hosts bands, poetry-reading, vintage trunk sales, and more.
Their wraps, salads, and sandwiches are fresh and yummy, and I haven't yet tried a sweet that wasn't delicious. They change desserts up often, so you have the chance to try pies, chocolate tofu tarts, cookies, and other things.
To top it off, they sell some food products, too: raw snack crackers or cookies, vegan marshmallows, chocolate bars, granola or energy bars, and plenty of teas.
Overall, not only can you find books and a place to study or hang out, you can also get good food.
Like another review mentioned, the service can be a little slow if they're busy, but they're more than reasonable, friendly people who are completely willing to work with your dietary needs.
Cons: slow service (if busy), limited seating
