I can tell you, though, that the onion kulcha is excellent: a layer of tender onions enclosed in light, moist, and crispy bread.
On a busy corner of Astoria Blvd. near LaGuardia airport, this place is, in fact, rather easy to miss. Tucked in the ground floor of an unprepossessing low-rise building, it's almost literally a hole-in-the wall. If you go, you'll be rubbing elbows with a bunch of New York's Pakistani taxi and livery drivers, who are almost always eating curries, not kebabs. I'm sure they're great, too (the taxi drivers always know where to eat) - I just haven't got around to trying them yet.
