I do tend to agree with some of the takeaway reviews here - it can be a bit 'hit and miss' at times but I put that down to them getting extremely busy.
Don't let this put you off either going to collect your food yourself or sitting down in the restaurant - both of which involve you getting off your backside.
We're fairly frequent eaters here and our dinner yesterday at The Coriander was superb. Amazingly fresh and full of flavour.
My usual is a Chicken Jalfrezi, Coriander Special naan (with chilli & cheese), Pilau Rice and their amazing Onion Bhajis.
Service is always good and I'd describe as 'businesslike'. You probably won't get much chitter-chatter from the waiters but then you probably don't come here to make friends.
