The UPSC Chatwallah shot to fame when he disclosed his real income under the Voluntary Disclosure Scheme during the Emergency. That was when the city woke up to his existence, although generations of young people taking the UPSC exams haven't missed his chat. For the discerning palate, though, his Bhalle Papri Chat won't taste any different from what's available elsewhere, but the crispy Gol Gappas will definitely impress you. Check out the chatwallah's Aloo Tikki and Faluda Kulfi for a complete meal.
