Also the chapli kabab IMHO. However this is mostly a "kabab place", which
the OP apparently doesnt want to go to?
More of a 'restaurant',
Sabri Nehari is okay, their nehari good. I also liked their brain masala, although overall I found the food rather rich and overspiced (not just 'hot').
Surprisingly nobody has yet mentioned Usmaniya, which is still my
personal "go to" spot on Devon. And Iam apparently not the only
one, since they are doing well enough to expand to a massive
spot across the street. It opened last week, BTW - I happened to
wander in last Friday eveningish, and it was their "Grand Opening".
Thus I couldnt order what I wanted to (goat biryani to go).. but
instead had to make do with eating Chicken Biryani, Chole, Naan,
and a pretty damn good Nehari in a buffet-style meal there, gratis

Apparently there was free food for everyone for the Grand Opening,
from "after prayers" (ie about 1:30 ish) to about 9pm-ish, I think.
And it was pretty good too - a fair crowd, so the food was replinished
quite often, not just sitting in a steam table setting.
Anyway. Usmaniya, above - also a restaurant, not just a cabbie
joint, and the best non-vegetarian Indo-Pak food on Devon overall,
IMHO

There's also
Chopal with good
sarson ka saag (mustard greens and spinach)
Iam not a vegetarian, and so have not tried their sarson ka saag

But
I can confirm that they have the best chili chicken in the city, and their
chaap is well spoken of. Good place overall IMHO.
Overall, if I was taking someone someplace, it would probably come
down to Usmaniya or Chopal. But of course thats just me - heavily
non-vegetarian, and happy to eat very rich (and often oily) meaty
dishes. Considering the mention of Jain food, the OP may well be
at the opposite end of hte spectrum - in which case a much better
balance of meat and veggies would be neccessary. If that is the
case, IMHO, none of the above (nor even the cabbie joints, or
Ghareeb Nawaz etc) would fit the bill - are all heavily meal-oriented
places where most vegetarian items can sometimes be a bit of
an afterthought. (Hyderabad House mentioned above, for example,
will often have *no* vegetarian food of any kind available - you
would be stuck with only rotis, plain white rice and dessert if
you happened to be vegetarian
