We ate twice here on a short stay in Madrid, the price was 12 euros for Sunday lunch plus the cost of the drink and 9.50 euros for a weekday lunch which was three courses and a glass of wine/water/beer or tea. This is amazing value, especially when the food is so tasty and the portions are a good size. There are some people complaining here that they serve fried food and non-wholefood items but this is a restaurant that is vegan for the animals not for some health fad, note the photos of saved farm animals on the wall. I became vegan to save animals and though I eat healthily most of the time I have no problem with being served chips/fries or white rice in a restaurant. This is the sort of place I want to eat, not somewhere that serves salad with everything whether it goes or not. To those moaning please remember there are many vegans who just don't want to eat dead animals and their by-products, they enjoy good, hearty food as long as it is vegan.
Anyway, the food we had was great, the starters were huge, I had risotto one day and a lentil stew the other and both came with lots of bread. For my main, one day I had a 'tasting plate' which had a bit of everything on it (including some lovely kebabs) and the other day I had meatballs with chips (fries) that was equally delicious. My husband had a carrot burger which he really enjoyed, also with chips. The choices are quite limited, both days there were three starters, three mains and a couple of desserts and on both days we both opted for the 'flan' for dessert. In the UK a flan is a kind of open pie but here it is more like 'Creme Caramel' so it came as a surprise when it arrived but it was really delicious so it wasn't a problem.
Overall I cannot recommend this place enough for vegans when in Madrid, it's very easy to find (just around the corner from Opera), it's clean and bright, has very friendly staff and great food. What more could you want?
Cons: Limited Menu, Can get busy
