Its better not to start a pub business. As per my analysis, 85% of business starts after 8 pm. I think in metro cities, it should remain open for whole night with good security and surveillance. Come on its not a bar or something. its like a restaurant. These questions always got a pause but yes its work out in many parts of India except south because many Indian people believes that the pub is place where youth took drugs, alchohol or other stuff which is a wrong perception. Many pubs in Mumbai are under police surveillance so nothing to worry about it.
