We have been here about 6 times in as many months and it is always fantastic. The food is simply delicious. My girlfriend has the green herb chicken karahi (packed with flavours) and I have the butter chicken with fruit and nut (deep and rich and the fruit/nuts make a great addition), usually with chicken tikka and potato pakora (it's a big portion) and a nice big, warm naan bread. We always leave stuffed and happy. We think the food is better than their tapas next door at the adjoining Mother India's cafe, plus there's no waiting in a queue for a table: you can book a table here, unlike next door.
The service is good, it's always friendly and quick, although it can get a little busy with a full restaurant (it's quite small) as well as others coming in for takeaway, but never to the extent that its a problem. They automatically bring a free bottle of chilled tap water to the table as soon as you sit down and as often as you want after that, which is a really nice touch. If there is a downside, it might just be that the decor is a bit simple inside, but it doesn't really matter when the food is so good. If you like Indian food, or just food in general, we highly recommend this place. It's definitely our favourite.
