Good cafe/restaurant shutting down in Nagpur, existing taste is getting bad, why?

So, Nescafé Illusions (both Traffic Park and Ring Road) and Kakori Conspiracy in Sadar have shut down. Haldiram’s food quality has dropped (tried Medical Square and Sadar last month). I used to love Paratha Shop, but the new one doesn’t taste as good. Also, Leaf Village Café near my office closed too. What’s going on in Nagpur? Why are so many good places shutting down, and why is the food quality at existing ones getting worse?
