The India Curry House in Algonquin is really great. They have a lunch buffet http://www.myindiacuisine.com/
It's very unexciting inside, small but really great food. They also serve an order of freshly made sizzling tandoori chicken with the buffet. It's located on Algonquin Rd between route's 25 & 31. It's located in a strip mall on the north side of Algonquin next to Butera.
