I ordered delivery from 309 from an online delivery service. I was a little wary after some overpriced bad experiences from Indian restaurants in Toronto, but 309 has restored my faith. I wouldn't call it authentic, but I would definitely call them DELICIOUS.
I tried their Mattar Paneer and Chicken Korma, with a side of plain rice. Everything was huge portions. Two people could not finish this over two meals. It arrived fresh and on time. Will definitely be a repeat customer.
