A friend of us recommended this place to us, so we went there. It seemed quite fancy to me, but maybe that is just because of L.A. :)
I had a combo of two salads (beetroot quinoa!) and a soup. I liked the food and it tasted really fresh and pure, but the portions weren't that big and for that quite pricy. My friend didn't like the food, she said there was no salt and no seasoning at all. But if you want some healthy food where you can taste all the single ingredients Cafe M is a good option for you.
They serve fish though, so not a complete vegan place. They could change that.
