One place which not many people know about, when it comes to decorative lights, is Bow Bazar. Covering stretches of Rabindra Sarani, BB Ganguly Street and Nirmal Chander Street, the place is filled with stores (Ivory, Smart Light, Lumen Art and Light Zone to name a few) wherein you can get fairy lights all under INR 40. The best part is, you'll get a lot of options to choose from. If you don’t like the offerings at one particular store, go ahead and check out the next one.
