Great once article overview of visiting India, especially if you only have a week or so. Do the Taj then get to places like Shahjahanabad to really see whats going on. As with anything, I would love to have a tour guide while I wandered around there, or even better, to be there for business.

It pays to be friendly to any sweaty, orange-glowing man you see perched over the fire-filled manhole of a bakery's tandoori oven.

Karim's restaurant, near the Jama Masjid, remains one of the best places to sample rich, if rather oily, Mughlai food. Try the mutton qormas with romali rotis and seekh kebabs, or, if you are adventurous, the mutton brain, if only to look at it sitting eerily in the middle of the table.
