On Friday at one o'clock I have eaten at Tsan. It is in a skyscraper in the second floor and there were many students and it was a little difficult to find a place. It was a self service with many different types of chinese food in vegetarian variantions. I payed for "prato livre" and a orange juice 18 reais. It is recommendable for who likes Chinese (asian) food. The Sushi was like some other sorts of food well made. I didn't like it that much because of the salad which was okay, the ambiance of a mensa and the service under pressure because of many students who wanted to eat fast.
