My British colleague loved Indian food, so we often dined at Bombay Palace restaurant in downtown Chicago. They served tandoori chicken with freshly made naan with stuffed onions and chillies. We could not get enough of that restaurant. One time I asked him if he would like to try a vegetarian Indian restaurant. He said not really because he probably will not find anything to eat there. But finally, he agreed to try it.
To make a long story short, on the way out of the restaurant he says, I can see why Indians can live on vegetarian food. There were so many tasty dishes to pick from in that buffet.
I liked Chicago’s Indian restaurants as well. I would attend IMTS at McCormick regularly during the 80,s 90,s and 00,s. Toronto has great Indian Food as well. Try Haakaa style if you run across it.
