A couple weekends ago, I went to the newish
Kohinoor Palace Indian restaurant across from the Dayton Mall. (It's in that shopping strip with the halal grocery and A Taste of the Mediterranean.)
The weekend buffet is more expensive (around $11-12/person, I think it was), but well worth it-- especially if you want to get a sampling of southern Indian cuisine. I was surprised and pleased to see dosas on the buffet line, nicely crisp and filled with a spiced lentil/potato mixture. They had something called "Sikh kebabs" that tasted like sausage with sauteed onions and peppers (very accessible even if you don't ordinarily like Indian food, IMO), a tasty chickpea curry, an
excellent goat curry, as well as the usual tandoori chicken, butter chicken curry (basically, chicken tikka masala), saag, lentils, pakoras, etc. Along with naan, they had a puffy deep-fried bread that was delicious.
It tasted/looked a bit more homestyle: the saag isn't pureed as finely, and overall the dishes seemed to be less rich than usual, which is fine by me. Even so, I didn't have room for a return trip to the buffet line. :) Everything was well-seasoned, but not particularly spicy.

Highly recommended if you love Indian food, and their menu isn't just another clone of Amar India's. (Which is also good, but I find their buffet a little bland and not as interesting.)
