The great sorrow of having to eat gluten-free is that you have to give up food serendipty: you can never just try some ethnic hole-in-the-wall, or food truck. And when travelling, you can never try the indigenous street food. (I came back from a recent trip to Turkey several pounds lighter, because every time I ordered "rice" it was actually rice with bulgar wheat in it, so I couldn't eat it.)
Chai Pani makes some of that great food available for people who can't eat gluten. The food is not cheap (not street food prices) but it is very good. The Uttapan and the Pakoras are great!
