There is no MacDonald is Dhaka. KFC and Pizza hut is available.
Other fast food shops are American burger, A&W, Arabian fast food, Helvetia, Chicken King, Wimpy, Bella Italia, Dominous Pizza, Western Grill, BFC, American Fried Chicken, Golpea Burger, Hot Hut, New Yorker, Sausly's and many more.
My favorite is the Portuguese chain shop Nando's. Then i also like Bella Italia (for pizza), Kings (Malaysian food) and Captain's world (owned by Bangladesh Armed Forces).
