For seafood lovers, the Fish Fillet Burger is a must-try in Kolkata. It features a crispy and tender fish fillet, usually made from fresh catch like bhetki or hilsa, coated in a flavorful batter and deep-fried until golden brown. The fillet is then placed inside a soft bun and topped with tartar sauce, lettuce, and pickles. The combination of the crispy fish, creamy sauce, and fresh toppings creates a delightful burst of flavors in every bite.
