We just tried Mazza (http://www.mazzaindianfood.com) for lunch on Saturday. It's at 2909 1/2 Concord Pike behind the Rita's (I tried to add a new restaurant link but it's not working.) Not much to look at - just a few tables and a couple of booths left over from its previous incarnation as a pizza joint - but we really enjoyed the food.
Went with the buffet which had four meat and four vegetarian dishes plus rice and a few desserts. It also included a basket each of freshly baked puri and naan. Particularly enjoyed a smoky Behari (Chicken) Kebab and a spicy Baingan Bhartha.
We chatted with one of the owners who was very friendly and very interested in getting our take on their food. She gave us the bad news that our previous favorite Indian hole-in-the-wall, Chingaari, had reportedly closed up. Mazza seemed to have a reasonable stream of customers both in-house and takeout/delivery for a rainy Saturday afternoon so hopefully they won't meet the same fate.
