Completely sortable drupal site

Hi there,

I am planning to make a site where i have a large list of restaurants, shop and events details(probably as nodes in drupal).
Is it possible to make a page where i can sort the restaurants/Shops with a field name Postcode or/and State?
Is it possible to make a page where i can show the clients the events happening on a particular week? particular state?
is it possible for me to provide my site visiter to choose from a drop down menu the "state_name" and see the restaurants in that state.

I would like to know whether all these are possible using drupal?
If i get an answer from you experts, i don't need to start my site in drupal, but if its possible i can start.

Just a precuationary question to avoid droping a project at mid way.

Thank you for your comments
