If you are a foodie, willing to drive and explore areas virtually ignored by most tourists, head to Kings Circle in Matunga (E) for authentic and cheap South Indian food.
This is a favorite with local South Indians, even in an area full of udipi places. Expect it to be noisy, busy and rushed, but the food is what you are here for.
Try the butter topped idlis, vadas, dosas and of course the filter coffee. Watch the locals pour their filter coffee back and forth from the metal bowl to the cup – the local way to cool your coffee down.
There is always a wait, so arrive early or plan to hang out for a while.
