Lahore has changed a lot in the 15 years but I still think the Old Lahore looks the same as my childhood days.
If you do go to Lahore - skip the new resturants, boutiques for a day and just reserve a day to go through anarkali, purani anarkali, badshahi mosque, sit in ricksaw.
iv bin ta badshai mosque wen i went ta pakistan an i loved it it wer gawjus ,and the rikshawz are exellent man apart frm wen u feel like wen ur gna fly of lolzz and wen ur legzz start to feel a lil ichy wen driven to fasy and the whole rickshaw vibrates lolzzzzz bt hav ta say theyr a laugh lol :-)
