Viva la Vida restaurant started in another place in Huertas, but the one I want to talk about is the one in La Latina.
A buffet of vegetarian food at weight and a market of organic products (pulses, cereals, vegetables, wine, oil...); and this all week long.
The truth is I went there very late and I could not have dinner, there was almost nothing left in the buffet but what they had looked very good. I did have time to have cardamom and soy tea while they were telling me about the dishes they you usually have and that change according to clients' recommendations. Moreover, I could have a look at the dining room downstairs, which is an explosion of colors and plants, very much in keeping with the spirit of the place.
It works as follows: you take what you want to have and you go weigh it. 100 grams cost 1.80€ and this way you do not waste food (problem of all buffets) since you pay according to what you eat and you can even snack and eat for 4€ some delicious dishes.
This is the concept that in my opinion is missing in the new minimalists restaurants: it is not paying a lot for little food, but paying according to your consumption.
I plan a special dinner at Viva la Vida.
