You have to give India House credits for knowing the Rockford preferences well. The longevity proves it. It has out-competed its only rival for a few months, Taste of India. While Taste of India tried to make it in Rockford, you would see mostly "exotic" people dining there--Indians, Middle Easterners, and Africans. It was like if you go to a Chinese restaurant, and you see mostly East Asians dining there, you know you have come to an authentic place. Alas, it was short-lived. After all, the "exotic" population is a small population in Rockford. Plus, most "exotic" people cook and eat at home. They don't go out to eat that often.
India House, however, dominates the predominantly white diners' market in Rockford. On any given day, when you go to India House, you will find mostly white people eating there.
The lunch buffet is extremely popular. You can go online and find buy 1 get 1 free coupons. Priced at $10 plus tax, you can get two buffets for only $11. And you can gorge yourself silly on food that seem different with unusual spices, and food that's not at all spicy. On any given buffet, you will have a small salad bar with several kinds of chutneys, tandori chicken, pakora, naan bread, soup, rice, chana masala, three different veggie dishes, a chicken curry in gravy, a couple desserts, and chai. None of these items is spicy hot.
The tandori chicken is usually reliable. The naan bread really should not be at the buffet table. It should be freshly made as needed. The chicken curry has too few pieces of chicken swimming in too much gravy. If a veggie dish involves paneer, such as palak paneer, you will find mostly palak and the paneer difficult to locate.
Still, there is only one Indian restaurant in Rockford, and it's nice to have one here. If you really want to get serious about Indian food, order dishes from the menu. Impress upon the owner that you want every dish made the authentic Indian way. Plead with him NOT to tone it down for you.
