I do not understand the negative reviews about this place, as it is truly fantastic! Maybe it depends on what type of food you are expecting. I find it to be the healthiest selection in London, and one of the select few restaurants which truly serves 'superfoods.' The all-vegan buffet features a selection of delicious vegan stews based on fresh vegetables, beans and other legumes, in a variety of creamy sauces (for example: stroganoff, chili, thai green curry, pumpkin stew, chickpea curry). There is a great selection of raw foods, including salads and many kinds of sprouts, as well as various marinades and sauces. There is always fresh steamed brown rice and/or quinoa as a plain grain (very macrobiotic style). There are always two soups as well.
The drinks selection is also great and really interesting: with all types of super-food infused shakes, chai, lattes, etc. As for dessert, make sure to get one of their cakes or yacon-syrup sweetened muffins (mmm blueberry)!
Cons: Staff Inattentive at Times
