Rawon is very normal beef soup made with keluak that can be found in East Java, Indonesia. For the first timer, they might be very disgusted due to the color of the soup. However, its worth to try as it is delicious.
For the rawon at Impian Wahyu, the rawon soup taste a bit too sweet for me that prefer a saltish taste. Inside has one slice of beef meat, and the rawon come with squashed meat aka Empal and Tempe.
One of the things that surprise me is the SAMBAL. The handmade chilli is super nice. The recommended food here bases on the owner is Oxtail Soup or Sup Buntut and Nasi Penyet
