PVR Cinemas — pricing for foods

I find the price of popcorn and coke to be absurdly high at pvr as compared to the price in market. I combo of popcorn and pepsi is charged 460 where the market price based on men should not be more than 150 rs

The cost of a regular salted popcorn is rs. 190 and cheese/ caramel flavour is rs. 220. The actual cost of the same amount of popcorn anywhere outside would cost merely rs. 20 or max rs. 50. Then on what basis is the cost of popcorn starting at rs. 190? Can't the government take any action on this
