I've been to Eden twice now and I must say it is a great vegetarian restaurant. They serve ovo-lacto vegetarian buffet at R$25,00 per kg, very cheap! Great chinese food and great variety. I've been longing for some chinese food after I became a vegetarian and this place answered all my prayers! You'll find fried rice, spring roll, "chicken" and vegetables on sauce and many other creations. Definitely recommended!
