Calcutta + Puchkas

There are some facts about Calcutta found in http://wikitravel.org/en/Calcutta that even I wasn't aware about. But the most interesting thing about the page, is under the "Do" section.
The last bullet says "Eat puchkas".
Then in the next section "Learn" right after that, it says "Eat puchkas only if you are a native".
haha..

http://www.schoolcircle.com/writenow/showcase/puchka.htm is an article written by a schoolboy about Puchkas. Makes me drool for puchkas now.
