To disprove 2 misconceptions-
1 - An Unamericanized Indian Restaurant has no appeal for Americans. These guys persist with spicy indian food and goras turn up in decent numbers.
2 - Intersect between good indian food and quick serve restaurants (QSRs) is zero. Wrong again, try any thing on the menu, chances are that it is nearly half as decent as best fare in your city back in india.
PS Ofcourse there are sentiments involved here and sub 10 USD lunch is always welcome :)
