I was there recently. It is a food hall place with a VERY limited menu. I had the Appam, Kadala Curry, Ishtu, Ghee Rice and Masala Biscuits. Everything was tasty; and moreover I have had these things for the first time in this country. The food is really well made, fresh tasting and the people running it are really nice. Plus they have a Temple Elephant ornament adorning the wall.

Appam is a Rice flour Crepe and it was cooked to order. It is as good as I remember eating in India. Ishtu is a Potuguese-Indian mashup that works really well (coconut milk based watery vegetable stew). Kadala Curry is a south Indian version of the Chana Masala, made with southie spices and the smaller variety of chickpeas called Kaala Chana. Outstanding. The Ghee rice is essentially a lightly flavored pulav with cardamaom, cashew and raisins along with the Ghee. Again, really tasty. Masala Biscuits is what we called Khara Biscuits in Hyderabad. It is spicy. I would rather get this to go and have it with some Hot Masala Chai rather than eat it at the place.
Everything was fantastic; and I will be going here often. The only thing I can try next time; along with the aforementioned; is the Egg Curry. I am a vegetarian so I did not try the Chicken curry.
