Bollywood Indian Restaurant Cadiz

We was 3 of us from Indian nationality. We ordered biryani with mutton bhuna gosht and mix salad first. Honestly that was not biryani. I felt Parwan pulao. Mutton was full of Butter chicken gravy. In between we ordered Naan Indian breads.
After eaten food one server came ask for feedback, so we are given genuine feedback about food. After that their behaviour was very rude. Suddenly they asked about our identity which is not ethical and then they start abusing us as a bad Indians.
1. Server don’t know what is service
2. They never ask about water
3. They were not hygienic
4. Washroom and kitchen door face to face.
5. Fried samosa was open inside kitchen which was visible from washroom.
6. Mix salad full of lettuce and 5 onions rings only

Your restaurant near by ship port that’s why peoples prefer otherwise as an Indian food and money wasted. I have bill copy but I couldn’t get upload option.
