Don't expect any frills whatsoever. In fact don't even expect to get seating. This tiny but popular South Indian vegetarian restaurant specializes in true-blue Iyengar cuisine. Some benches and tables make up the seating, and the place is packed most of the time. Be prepared to wait. But since there is no lingering as such (you go there to eat - not to soak in the atmosphere), you will probably find a place pretty quickly.
Absolute best bets are the puliyogare (the tamarind rice), the kanjeevaram idlis and the fantastic, melt-in-the-mouth best-ever sakkare or sweet pongal.
Prices are low and a meal for two is approximately Rs.100. A small price to pay for fantastically authentic food!
