A lot of time they have biryani per-made. They just make you wait to make you think that they are actually making it. Look under he samosas to see if its pretty made. Also they are sort of slow
Haleem don't even try. Tastes like lentil soup, seriously!!! GI tag for Haleem makes perfect sense now, else the chef would claim this less than mediocre quality item to be Hyderabadi Haleem
