Bad attitude, poor service and food and rudeness

We visited Banjaara restaurant last week Friday. we always book big groups of people at the restaurant but on 2 occasions one last year Nov 21st 2014 and the 2nd 10th April 2014, we visited with more than 12 people and our bill higher then 1300 both times, we find that we get very poor and bad attitude from the hostess and waiters there, they service is poor and slow, and once we eat they want to clear up the tables and keep on coming to ask us if we ready to leave, we noticed this on 2 occasions now, apart form bad service the food quality is poor and has dropped considerably, we do not only purchase there in big groups, my family and I often eat there or get take out. The curries are far from a curry its filled with tomatoes only, I found a hair in my tandoori chicken. I also noticed they don't treat their other customers this way but only the Indian patrons that go there, we understand majority of their clientele is not Indian but on Friday we where the only group of Indian people there and them being Indian treated us very bad, but they did not treat the rest of the people there the way they treated us, they kept on giving us the look to leave we will no longer support them.
