Google doesn't care about Durham, Many Bar times on google maps are wrong or incomplete. The idea of the app is to bring information from maps and Facebook at college sites to give the bars in Durham.
Open the webapp and it remembers your settings and shows you the next bar to go to (based on distance, opening time ..) Or go onto the list of bars to see more details Or Plan a bar crawl
Here's the fully fledged app http://bartendur.net/
..... on second thoughts, maybe don't use it next time you need to make it lit, we couldn't get the backend fully functional in time.
