OK folks, here's the dope on SIMBLY SOUTH--it's excellent and cheap. Located about 500 meters from the main gate of Deshbandhu College on the main Kalkaji Rd. (H 3B Kalkaji). The menu features veg. and non-veg. items from Kerala, Andhra, Tamil Nadu and Karnataka. So far we've tried various veg. Kerala dishes -- including avial, cabbage thoren, olan etc. -- and they were both authentic and delicious.
Like most Delhi dives, the joint delivers, but despite being called a "hole in the wall" by one of the weeklies, it actually has a nice, clean diner-like interior and is far from a dhaba. Staff is polite and efficient. Southies, of course!
Can't wait to try the chettinad prawns and Kerala-style biryani. Great addition to the CR Park / GK II / Nehru Place environs.
