Heaven for UPSC students staying in Patel Nagar. If you are within Patel Nagar - Karol Bagh axis, visiting this "Chai Factory" is a must for the strong & extra caffeinic touch this chai has.
I personally used to gulp minimum 5 teas a day during my hectic preparation in chilly December, temperatures soaring below 10°C. & the relaxation I get after a hot tea sets me up for the next hour of preparation.
The owner of the tea stall is really friendly & you can throw in a conversation or two if you are bored.
And finally, it's like an abode to me because I'm a heavy tea drinker. For normal tea drinkers, I have only one word, you'll not be disappointed.
