It was on busy weekend i have been there in Rasa W1, without a reservation. The staff were very cooperative and offered me a table on the first floor without much delay. The first floor looked better with the keralan antiques and paintings.The food was amazing and without any doubt i can say the best indian meal i ever had. They have a variety of vegetarian dishes as well, which my wife liked. She had a veg feast with snacks, starters, 5-6 curries, rice, bread, and rice pudding for just £ 19 ! While i tried their king fish curry with boiled cassava and it was best combination. The staffs are pleasing and cooperative. Highly recommended!
