My last visit to Chowki was a terrible experience.
I ordered a Festive menu which tasted was good. But towards the end of my meal I found a piece of Glass( the restaurant claims its plastic) in my rice. I was obviously annoyed by the experience and raised it with the Waiter. One of them checked the piece and verified something in Kitchen. He told that it wasnt Glass but clear plastic , though neither of it should be found in food. Till now all was fine as it could be a one off mistake.

But the problem is the Manager, he told us that we need not pay the bill and he was sorry . Once we were out of the restaurant , to my surprise ,he told that it wasnt Glass and I shouldnt have reacted the way I did .
So my conclusion is , the manager of the restaurant expects foreign bodies like plastics and glass in the food , but customer should react according to the material he/she found.
