Oh God yes. Especially the Goan curries - the Chicken Peri Peri is as good as it gets. My wife swears by the Dansak (as do I - she can never finish it) and we've tried loads of their other dishes without disappointment.
But their Onion Bhajis are not recommended.
Nishat Tandoori - Preston Street. I've been using it for about 20 years, and it's still as good as it ever was. I've never found anywhere that gets near it.
