As I finish final preparation for my Agra trip in a couple of weeks I have a couple of questions that do not come up in any searches. I am traveling with my sister. From the travel books I have read I understand we can both expect a lot of stares no matter what we wear. We want to be comfortable but do not want to be rude. Here are my questions:

1. Is it true that most locals do not wear shorts?
2. It is my understanding that while people might not have an issue with me in shorts, if my sister is wearing them it might be considered rude. Is this true?
3. We are doing strictly tourist stops, is their a dress code for the Taj Mahal?
4. We are having dinner at Bukhara, are jeans ok, or should wearing khakis?
5. We are packing real light and just want to bring one pair of shoes, are sneakers ok?

Bonus question while I have the floor, we are spending one night at the Mughal Agra. Everything I have read here about the restaurants at the hotel says they are sub par. Anyone have a dinner recommendation in close proximity to the hotel?
