I've studied at "La Sana Gola" for my basic cooking lessons.
I learned the basics of macrobiotic, and when I get the chance I go there for a different lunchbreak.
The place is very minimally furnitured, an essential style, just like their food.
Dishes are always well balanced, even if it may be a bit pricey. Anyway, with 12 euros you can get away with a healthy, vegan lunch.
Choice is not wide, but it all the food is freshly made, and mostly whole.
Cons: Cold atmosphere, Not a wide choice
