Visited the restaurant late in the evening and there was another couple dining there when we arrived.
Ordered our food, but waited for at least 20 - 30 minutes before it arrived. The wait was made worst due to mosquitoes' bites, most probably due to mosquito breeding in the plants surrounding the whole restuarant. So do come prepared with long sleeves and pants or spray some insect repellants on exposed skin.
Surprisingly they make very good western food, one of the best I ever had while in Yogya!
Will definitely be back if I ever visit Yogya again.
