my rating of 3.0 is for the ambience and location, which is very close to famous sultan ahmet mosque.
in terms of food, it doesn't impress you very much. since they use the word 'ethnic' in their name, i was really looking forward to my dinner. after all, i was going to have indian food after almost a week.
i didn't like the biryani at all. i am very sure that it shouldn't be called biryani. it lacked the signature fragrance and cooking style. at best it was a 'masala rice' (spicy rice with some bits of vegetables). the paneer (indian cheese) used in main course should have been a lot creamier and softer.
veg. spring rolls were fabulous.
we chose to sit inside, and we were the only ones sitting there, while all tourists were sitting outside and enjoying the weather. well that is still no reason for why there was not even a single staff person to attend to us after the first order. my wife had to get up from her chair between our meal and call someone from outside to attend us.
for the price that they charges, which is just right, i expect them to deliver at-least 90% of what true indian food tastes, smells and feels like. and trust me, istanbul has all the ingredients locally available to do that.
i will still visit them next time and see how better they have done.
