Gary and I recently had lunch at taxi hangout
Hyderabad House. Another Indo-Pak taxi hangout is on Ridge Road in Chicago. If you follow it (from Evanston into Chicago) along to the area where you turn left under a viaduct, then just before this intersection (maybe 1/4 mile back) the very last business against the railroad embankment is another restaurant oriented toward taxi drivers.
BTW, this place used to be "Blue Diamond". I think it is now "Bismillah"?
(It used to be very much a cabbie joint, decent food but really quite
unconcerned about heath or hygeine. A good buddy of mine, or so
we always teased him, was responsible for the poor guys being shut
down

Basically what happened was this - friend, Indian chap, was a
grad-student at NU. The two of us were doing something on Devon one
early evening, and we rolled up to this spot and tried it. The bihari kabab,
I think it was, was really pretty good. So this guy goes to school the next
day, and some professor asks him if he knows any good authentic Indian
spots. He says "oh yeah, I ate at Blue Diamond yesterday, very authentic".
Silly chap. The professor notes down directions, promises to try it out
the next day... and three days later, when we go back there to get some
more Bihari Kabab, its been closed by the Health Department

My friend has
never lived it down - every time we eat at a good cabbie-joint-type
restaurant since, *someone* has made it a point to warn him not to
tell his professors about the place or they'll have it shut down too

Unless someone can advise better, you will have to do some personal investigating because breakfast at Indo-Pak taxi restaurants is largely unexplored. I do hope as you make your rounds and explorations, you will keep us advised. We want to learn with you. Even if it is not what you desire, we love adding more information to the body of knowledge called LTHforum.com.
BTW, I disagree that the breakfast at the cabbie joints is unexplored - Ive had
dozens of breakfasts at em myself
I dont really know of a cabbie joint that does dosas or idlis anyway - thats
veggie stuff, and anathema to any good cabbie joint. There are times when
there is literally no veggie item on the menu (I know, Ive been there with
vegetarians sometimes - and on the bad days all they had to eat was the
watery daal thing that came as a side to my meat-entree

Ive never
seen anything like idli or dosai at any of these spots (though, thinking
about it, the one "cabbie joint type" place that might have something
like this may well be Ghareeb Nawaz - they are beginning to put a few
more veggie-style items on their menu. Though I really doubt they have
idlis or dosas either. But they are the only cabbie joint that one might
have any chance of getting something South-Indian).
I dont think there are actually any South Indian places that open so early
in the morning - thus leaving Chicago with no idli-dosa for breakfast
at all. The earliest, I think, that one can get that sort of stuff in Chicago
is probably about 10 or 11am if one is lucky.
This is also, sadly, the case for "non-veggie Indian breakfasts". One of
the best breakfasts Ive ever had is "Nalli-Nehari" and "Kheema" - in
India. Nobody does Nalli-Nehari in Chicago at all, a few places do
Nehari - but they dont open till about 11am or so either. The cabbie
joints *sometimes* do Nehari too - but it is often not as good, and its also
done as a menu-item for dinner, and they might have some leftovers
for breakfast. Nobody does a "nalli-nehari and kheema" breakfast
per se.
