First of all - this is a great place. A mix of bookstore and a restaurant with a beautiful interior and cozy outside sitting.
The place is called Soma Book Station now and if you care for good music and atmosphere then this is the place to be. Other than that, this is a regular restaurant with lots of meat options, some vegetarian options and well, hard to find real vegan options. You might be able to get mixed beans salad, hummus and bread (no saying whether the bread is vegan), and salad with quinoa (with almost no quinoa in it and no saying whether the sauce is vegan).
To sum this up, if you are going for a drink this is a good place, if you want food, you are better of going to a Thai restaurant or newly opened green & protein food bar. Unless of course, you want to spend your evening wondering how many vegan points have you just lost.
