This is a nice book shop/cafe in downtown New Haven. They don't have too many vegan options, but they do have a home-made vegan burger and a home-made vegan baked good.
I had their veggie burger ($8) which was pretty good. I liked the toasted ciabatta bread and the substantial heft to the dish. Everything felt fresh and well thought-out.
Why not offer a soy-marinated tofu sandwich, though? Or a juicy seitan burger? I think Book Trader is off to a good start but could definitely stand to up its offerings on the vegan side of things. They clearly have some talent in the kitchen to make this happen.
