I was excited because of the all-you-can-eat buffet idea, since in Brazil it's a very common kind of restaurant and I hardly find such a thing in Europe. But I got disappointed about all that oily food that slips in the plate. They could have more salads and don't put oil in everything. Also, water shouldn't be charged. It's not awful, but Madrid has other vegan places to go that are way better than Shi-Shang.
And why do they not give up jelly and yogurt and become a vegan restaurant? It's an easy step and nobody will stop going there because they don't sell jelly or yogurt anymore.
Cons: Oily, Few options of salad, Jelly and yogurt aren't vegan
