The food isn't terrible. That is the best I have to say. We cook Pakistani and North Indian food at home all the time, which is what this ostensibly is. Every damn dish tastes the same here. This type of food is supposed to be rich and nuanced, and every dish should have its own set of flavors that make it unique. I really wonder if they just have a base curry sauce in the kitchen, and throw whatever combination of meat and veg in when they get the order. I'd rather eat my own versions, thank you very much, and I'm not even the desi half of the household!
Go to Annapoorna grocery, buy some spice box mixes, follow the instructions on the back, and you'll probably do better.
