The sweet and sour fish at 黑社會 was delicious! There were chopped melons instead of the usual pineapple as garnishes, and there was not an overwhelming amount of red and green peppers as is normally found in sweet and sour dishes. The fish is deep fried with batter but is not too oily. Last but not least, if you visit this restaurant on sun-thurs after 5:30 pm, they have a menu featuring dishes that cost only s$8.80 (including this dish!)
