The picture tells us about Rawon Setan (Devil's Rawon). The only reason for this nickname is because the warung (stall) is open in the midnight to dawn just like the time when devils come out. The Rawon Setan stall, is quite popular in Surabaya. We can eat the Rawon together with some additional side dish such as fried lung, kidney, or brain of a cow.
