I went to Mina for the second time last night. The food was definitely a notch down from the previous wonderful experience. I hope this was an unusual event and not a sign of decline. The vegetable pakora was good (but I really missed the green sauce) and a goat & spinach dish was also good (I don't know the name). The palaak paneer was the main disappointment - entirely different from before.
On my last visit, I also had a really cheerful waiter who was delightful. I think the nephew of the cook. Last night, we were served by the owner ... a much slower experience, although that didn't bother me.
Oh - my friend also asked for a dish to be spicy but it was not.
