The vegan burgers are ok - I just don't really get the concept of rather healthy organic burgers, because if I want a burger, I want a fat fast food style burger. If I don't want that, I have something else altogether.
But still, the vegan patty tastes good (even though I would like a more "traditional" burger patty made of soy and wheat or something, as an option) and there are plenty varieties (with avocado, cole slaw, different herbs, fancy mayonnaises, ...). All the sauces/dips are vegan, too. The salad dressing isn't made with cow's yoghurt but with silken tofu. I really appreciate things like that!
The fries and sweet potato fries are also tasty. I'm not sure whether the onion rings are vegan, too. Another vegan option is Chili sin Carne, and they have vegan lunch deal, breakfast and kids meal options.
Cons: A bit expensive
