Diamond Hotel lost his Originality

Overall it was an average experience. Diamond Hotel was not like same as before. 

It was famous for Butter chicken, Biryani and Chilli chicken but sadly the taste was missing which we were used to. The thick red gravy of Butter chicken was not there it was a simple Butter Chicken that we can get anywhere. 

Ratings :- Service - 1/5, Food - 3/5, Ambience - 4/5, Taste - 2/5.

Suggestion to Restaurant:- Please look into your service, it was not as expected and if possible can we get the older taste of Diamond Hotel for which it was famous. 

If yes, I will definitely come and try once again.
