This was the first vegan restaurant I visited in Bremen and I enjoyed it very much. It is just a small restaurant, but it's really nice and the owner is very friendly and explained the menu to me. There were also some non-vegans there who were quite confused and he took the time and explained everything in a very friendly and patient way.
The menu is somewhat limited, the hot dishes are vegan döner, falafel and a soup of the day. There are more things like potato salad, chips etc., and for the main dishes you can decide between different options, e.g. falafel with salad, falafel in a pita bread etc.
The soup was a potato and kidney bean soup and it was really delicious. The falafel was also very good and fresh, and accompanied by a fantastic, hand made sauce.
There are also many organic drinks.
The prices are very good as well, my bill for the falafel pita, the soup and a drink came to 11€, which is rather cheap.
The location is ok, it's about a 10 to 15 minute walk from the central station. Service is really quick, so I really recommend it if you arrive on the train and want some nice vegan food very quickly :-)
