I am very close to R city and last when i visited R city , the Foodcourt was under renovation that was abt 15 days back .
I guess we should look for a place which will be less crowded , Food court on a sunday will be very crowded and hence i suggest we move to United cafe bar( slightly expensive) , which would be less crowded than other dine in restaurants in R City. There is sals pizza (Pizza + Drinks + Cheap) on way to Powai , which is usually empty and not that expensive too , rest take your call. Assuming we meet for 1.5-2.0 hrs , we should look for a place which does not get high on demand on weekends.
