Best Practice Url Direct Multi City

[RedMacGirl]

I am wanting to learn the best option to enable our web site visitors to select their city location from our homepage (index.php). Is a drop-down menu with links to the cities (eg: my site/newyork.php) with new content and links for that city way to go for this? Or should selected city page reload in the same index.php page and display new content with a jquery load function? Two different approaches and not sure which one is better practice. Look forward to your response.
