Science City is 3 mi (4.8 km) from central Kolkata, why not stop by during your stay. If you want to experience more of the culture Kolkata has to offer, head to Acropolis Mall, Ruby Hospital, and Salt Lake Stadium.
Imagine soaking up the atmosphere at Salt Lake Stadium, a stadium in Salt Lake. If you think Salt Lake Stadium is cool, you also might like Eden Gardens and Netaji Indoor Stadium, both located nearby.
If you want to give your credit card some exercise, head out to Quest Mall in Ballygunge. Splash some more cash at Forum Shopping Mall and Camac Street.
If museums are on your list of things to see, you might want to browse the collections at Missionaries of Charity's Mother House in Taltala. If you want to see more of the museums in Kolkata, Victoria Memorial isn't far either.
