Comesum — Veg biryani

I was travelling to harpaalpur from nizamuddin railway station via up sampark kranti. There was no pantry car in train so vendors from comseum were roaming for selling food, we both a veg biryani and got a bill as well but once we open it and ate a bit, taste was so bad and it was not eatable. Biryani was stale and smelling bad.. We are so disappointed from such a brand comseum.
