In my opinion this restaurant project is going to increase the amount of tourist and local visit CVP. CVP itself is one of the best place to visit in Islamabad, and will provide a better future hanging out place. This tourist spot will improve the vision and thinking about those people who still think that the capital is just a tiny dot on the map of Pakistan. But on the other hand increasing tourism will have it negative impact, that is increased traffic, increased pollution, effect on wildlife etc
A suggestion in my mind to decrease the traffic would be by introducing 'chair lift system'. It will be a good experience for tourist and locals to have a fly bye experience throught the greenish margalla hills and on the other hand generate a good source of revenue for CDA or any private organisation.
