Fried bombay duck fish(Bombil) Its a super soft fish and the best place to have it in Mumbai is Gajalee. Bombil is also known as Bombay Duck owing to the fact that it’s presence is found in and around waters of Bombay (Mumbai). For the benefit of those who reside outside of Mumbai, let me clarify Upfront-Bombay Duck is not a duck but a fish. It is definitely one of the most popular fishes for Mumbaikars. Particularly during monsoon seasons when fishing is stopped in sea water of west coast, Mumbaikars prefer buying dried version of this lizard fish. During summers the sight of Bombil suspended with a rope tied across poles to dry up is far too common if you happen to be in Mumbai.
