If, like me, you like a drink, and have a GPS and Java Enabled mobile, the following software could be handy.

It searches the Good Pub guide for pubs local to you. It can also display reviews of them. It's far from perfect (the database of pubs isn't large), it costs money (50p for the software, 50p for each review and 20p for each search), but it's a good start.
Now, if only I could find an app that would automatically direct me to the nearest train/tube/dlr station or bus stop and download timetables for me..
