Lereng Agung is a tour bus stop in the middle of nowhere, up in the area of Besakih Temple. It is your typical tourist restaurant with nobody but tourists in the restaurant, serving nothing but a buffet for lunch. The buffet costs 70,000 Rupiah ($7.00 USD) per person, I think one reviewer got confused, and contains mostly bad Chinese food, but also some edible things like Noodles, Fried Rice, Fried Chicken, Pork Satay, Spring Rolls and Soup. The Chinese dishes were overcooked to the point of hardness, and like most tourist food in Bali totally tasteless, but put some Sambal and Chilis on it and it all tastes ok.
The only reason to stop at this place is the view over the rice fields with Mt. Agung looming beyond. We thoroughly enjoyed watching the breeze through the rice fields, watching the farmers and work, and just marveling at the beauty of this part of Bali. We didn't even care that the food was bad, it was a nice experience nonetheless. Of course they expect you to buy something if you walk into the restaurant, it's a business not a viewpoint, that is to be expected. Stay a while, have a drink or something to eat, and enjoy the scenery. The service staff was really friendly and eager to please too. Bathrooms are some of the cleanest in this part of Bali, even automatic flush, but may not have toilet seats.
One bizarre thing was a giant fruit bat hanging out right outside the entrance. Huge. Looked like Batman. One of the staff was feeding it watermelon.
