I have heard that the Chettinad restaurant Karaikudi is open now. It is in the Lottes Plaza shopping center. For me it is always exciting to find Indian restaurants that go beyond the prototypical Indian-American faux Mughlai-Punjabi genre, and to try restos that serve an authentic regional menu. We have a lot of South Indian (Tamil and Andhra) snack shops, but this place has snack items plus a full menu of dishes.
I trust anyone interested enough will google. But the Chettiyars are a Tamil Hindu community and Chettinad is one of the regions where that caste community lives. Chettinad is famous for its food: non-vegetarian food. I am no expert on Chettinad cuisine, but I have had Chettinad chicken and Chettinad style biryani before and really enjoyed...very very different from any typical North Indian type 'curries' that you may have had, really something interesting for CHers to try especially if you enjoy South Asian foods.
Some stuff that I want to try: kottu porotta (shredded up, seasoned, stir fried whole wheat-white flour mix flat bread. Keema dosa (all of the many S. Indian dosa houses in the DMV are pure veg, this is an interesting opportunity to try a non-veg dosa.), and of course, their selection of mutton, fish, chicken curries done in the Chettinad regional style. I also love sampling regional versions of sambar, so I want to see how theirs differs from other styles I have had. I see they have 'thali' plates for trying a handful of dishes at once.
I plan to go soon and report back (I have high hopes that this place will really deliver), but I thought I would give NoVa hounds a heads up just in case anyone is inspired to go try the place.
