(sorry to hijack, but I'm learning something here, please humor me for just a sec..)
I wouldnt consider them more or less Indian than anything else - theyre all Indian, just different kinds of Indian

Frankly, to me (having grown up in India), when I think "curry" what comes to mind for me is coconut-based curry - which I suppose is maybe from the southern part originally (though I didnt grow up in the south). Thats a very Indian curry - just more prevalent in the south.. its what is usually referred to as "curry" in India, though, and a lamb version is not the default-style (maybe more fish, shrimp etc instead, even egg). Similarly, korma's and makhani's are authentically Indian too.. but from other areas. Makhani I would not consider neccesarily a "default curry" for Indians (not referred to as "curry" in India for one)- but it is the most common form of gravy-dish in the Punjab and north India, a very large area and for a large population. And, as Athena pointed out, most often available in Chicken form - ie Chicken Makhani, or Butter Chicken (famously from Ludhiana in a book title recently discussed on here

is the sort of iconic dish (you dont really hear of "Lamb makhani" much, in contrast).
To me, kadai-gosht would very much be a standard Indian curry in that broader definition, the one Iam likeliest to eat personally... but then thats because the most *popular* non-chicken meat in India overall is goat, and kadai-gosht is basically the default "goat-gravy dish" you'll get in many places. Lamb is much rarer in India in general - most popular in places like Kashmir, but really not very prevalent in the rest of the country. In terms of non-chicken meats-in-gravy-dishes, Id say "kadai gosht" is probably the iconic dish in many parts of the country.
Put it this way - if youre looking for a default lamb/goat "curry".. IMHO kadai-gosht (at Usmaniy for eg, oily in a good way, non-creamy, spicier) is the way to go for most Indians. If youre looking for a default chicken "curry".. maybe Chicken Makhani (creamy, lighter orange in color, very non-spicy) is the way to go. If youre looking for default fish curry.. then Fish Curry or Shrimp Curry is what youd look for on the menu in India (and you wont really find a great version of those anywhere in Chicago, I dont think) - non-creamy, coconut-based curry, usually hotter than the first two.
For the OP's question, a lot of the above is probably not hugely relevant

For the person who has eaten Indian food only about 3 times... my guess would be that its probably the ubiquitous "Mughlai style" thats been consumed - ie tandoori chicken, creamy-non-spicy-butter-chicken etc. For that, Tiffin or India House are probably decent bets on Devon, and would provide a familiar-ish taste. (Id still suggest taking them to Khan's or Usmaniya instead though

Usmaniya is a friendly enough place in terms of decor and "look", and the food is really quite non-spicy in terms of heat - request especially non-spicy there, get a kadai-chicken or kadai-gosht and my guess would be that the non-Indian-eating friend might handle it quite well).
