The naan stole the show. The nan alone gets one star. It was of the thinner more crispy type, not the thick fluffy type. Three stars for the curry. I did not think it was better than the other smaller Indian places around Calgary.
Personally, I prefer the smaller mom & pop Indian restaurants. Royal India would be good to host banquets or company events, the place is huge and even has a dance floor.
Overall, the experience was not bad and I would go back.
