RDB Cinemas is one of the cheapest multiplex in Kolkata. It is located in Salt Lake Sector -5 . Sector -5 is the official area of Kolkata. So, you can expect low traffic @ RDB. Now, lets talk about this multiplex. I watched 3 to 4 movies in this multiplex(1 3D). Picture and sound quality is okay but not awesome. Ticket rates starts from 90 rs at week days and 150 rs. at weekends. 3D movies are 20 rs. higher than 2D movies. As I told before, its quite lower than other multiplexes around the city. Food and other stuffs are also quite low. So, at a very affordable price you can watch a movie.
