Try Varanasi,it’s in Battersea . For me it’s the prawn dishes they do that I cannot get enough of. I tried many Indians and eventually settled on Varanasi,it’s the best!!!
Akash used to be good but has slid a bit in my opinion. Had some Rajah Rowing and Bombay Bike recently, they have been decent. Go to would be Indian Ocean just off Wandsworth Common on Trinity Road. They all deliver.
