Punjab Grill, Lite Bite Foods Pvt Ltd — served non-veg instead of veg

Address:	Gurgaon, Haryana

We went to a Punjab Grill Restaurant today, which is in Gurgaon in Ambience Mall, one of the well known restaurant. we went there for first time and ordered Veg Paneer Lababdar, after eating some bites we found so many small pieces of non veg in it.

We are strictly a vegetarian Brahmin, due to no fault of ours we were cheated into eating a non-veg meal. This has hurt our religious sentiments.
Its more of this than the non veg fuss. We expected them to understand this and apologise which din’t happen.

I want to know if I can sue them/teach them a lesson in any way.
