This is the best Indian restaurant I've been to in Champaign-Urbana.
At least, better than the other two I've visited: Sitara and Bombay. I've not been to others. I like them all, but Kohinoor is certainly the best.
I had the fairly-spicy lamb dish and onion naan. The meat was tender and every part of the meal was extremely flavorful even down to the sauces on the table.
