I'll say something you've already heard by now -- It's a very well written piece -succint and succulent!
Congrats!!!
I also liked the way you clarified the diff. bet a Southerner and a Madrasi.
In my experience Andhra Bhavan was "the Find" of my Delhi visit when I was there for my Fulbright interview. I went there all the way from Hayes Road for the duration of my visit.
For the Andhraiite missing the touch of home, AB is the place not just for the meals but for the flavour of Andhra (and I don't mean just the culinary one).
I feel one must visit AB, if only for the service and hospitality which is sure to warm the cockles of many an Andhra Heart.
