To begin with, the place is not a restaurant, but that's not a surprise. The location is not the best one, because it is close to a market which attracts roma people and illegal immigrants. If the cafe was just 500 metres away on Vitosha pedestrian area it would be a massive hit. I would say it is small place, though the interior is very nice. There are vegetarian and vegan options - they prepare super delicious raw cakes and organise classes for just a few EUR attending fee.
