This is a south indian restaurant generally known as the Suvai.
The food is South Indian rather than the food available in many curry houses. Alcohol is not served though I believe you can bring your own in.
This restaurant sells a wide range of south indian dishes including Dosas with various fillings and the curiously named Chicken 65 which is spicy battered chicken. They also sell a range of south indian curries and various rice dishes. The quality of food is excellent with plenty of fresh spices being used. You would struggle to spend more than £15 per head in this restaurant and you can probably eat quite well for £10. It is also worth noting that there is a big range of vegetarian options on offer.
I was recently in this restaurant with a friend who had a guide dog and we had no problems.
If you are looking For quality of food and value for money this restaurant is truly hard to beat and I would highly recommend it. English can be a little difficult and there is not always everything available that is on the menu but it's worth it despite occasional disorganisation.
I am happy to give this restaurant 8 out of 10.
