This place serves some really good food at reasonable rates! i am a veggie and i still didn't have trouble finding some variety here. I had the tandoori gobi and I would definitely recommend it. Quite a few tandoor options for vegetarians here. My Dala made it even better by offering a 40% discount on the bill. Avoid the biryani. its really just rice with no flavour and sparse vegetables.
I am very fond of the curries made by Royal Kadai restaurant. Their starters and soup are also very good. The main course/roti are okay types. Many of our neighbors used to arrange dinner here for small parties like kids birthdays and other small occasions. This is a very popular restaurant in the neighborhood among the residents. probably that is what makes royal kadai a famous restaurant in jayanagar area.
There are some comments about Royal Kadai restaurant that they have to pay by cash. But usually they accept credit and debit card as payment options. Probably there was some technical issue on that particular day. But I have paid with my debit card about 2 months back at this restaurant.
