One time I brought a couple friends to Priya, who'd tried curry and other Indian cuisine in England. Expensive, top rated, restaurants. They said the phone was as good, if not better than what they've had.
Never been disappointed, and is safe for allergies (I can't have gluten... I lust after the smell of their vegetable somosas). I always get the chicken tikka masala, and they're carrot halwa and rice pudding is amazing. The only thing I WISH they had was coconut soup, but it's probably better they don't since I'd eat way too much of it.
Also, the buffet is incredible. Easy five star rating!
